), ( Planets form when material in space starts to bump and clump together. Take an interactive tour of the solar system, or browse the site to find fascinating information, facts, and data about our planets, the solar system, and beyond. First, make sure there are no obstacles around that you might bump into. A planet's gravity pulls equally from all sides. Speaking of exoplanets, those are off the table for … ), ( Secular astronomers had expected that other solar systems would resemble ours, with small planets forming very closely to their star, and large planets (like … A planet's gravity pulls equally from all sides. ( Factoring out the radius we get. ), ( The eight planets in our solar system differ in lots of ways. 2 When a forming planet is big enough, it starts to clear its path around the star it orbits. Since they're not even one whole percentage point thicker in the middle, it's safe to say they're very round. Jupiter is 6.9% thicker around the middle. ), ( This verseteaches that God has inscribed a circle on thesurface of the waters at the boundary of lightand darkness. Then either while standing, or in a spinner chair, spin around in circles. 9 So bigger planets will be rounder. ), ( The links are provided, or you can search in google/youtube for "we are the planets big and round", there are a lot of "planet song" otherwise :) The first link has partial lyrics on screen, the second has a slightly different animation and only planet names on screen. ), Post Comments The IAU planet definition also put other small, round worlds into the dwarf planet category, including the Kuiper Belt objects Eris, Haumea and Makemake. Along the equator of a planet, a circle half way between the north and south poles, gravity is holding the edges in but, as it spins, stuff wants to spin out like mud flying off a tire. Our Solar System’s Planets in Order. As they spin around, they bulge out along the equator. Atom A ring system around a planet is also known as a planetary ring system.. 5 Gravity pulls from the center to the edges like the spokes of a bicycle wheel. Saturn bulges the most of all the planets in our solar system. The rings around Jupiter, Uranus, and Neptune are much smaller, darker, and fainter than the rings of Saturn. Also the bigger the planet, the stronger the gravity. It is thought to be halfway through its lifetime. We are the Planets Big and Round Watch us Happily Fly Around . In this solar system map you can see the planetary positions from 3000 BCE to 3000 CE, and also see when each planet is in retrograde. Saturn is 10.7% thicker around the middle. 6 Why aren't they shaped like cubes, pyramids, or discs?Planets form when material in space starts to bump and clump together. ), ( Saturn and Jupiter are really big and spinning really fast but gravity still manages to hold them together. This makes the overall shape of a planet a sphere, which is a three-dimensional circle. The axis rotation speed across the planets varies and this is why the ages in the boxes above are different. Some are small and rocky, and others are big and gassy. They aren't perfect spheres, but they are rounder than Saturn and Jupiter. We are the planets big and round Watch us happily fly around We are the planets big and round Watch us happily fly around I'm the largest planet I'm Jupiter Jupiter I'm the planet with the Rings I'm Saturn Saturn I have 27 moons! ), ( ), ( 7 While you don’t notice it, the earth is also constantly changing its shape. This boundary between lightand darkness (day an… ), ( Things along the edge have to travel the farthest and fastest. Uranus is 2.3% thicker in the middle. Why is that? 31 1 Consider Isaiah 40:22 which mentions the “circleof the earth.” This description is certainlyfitting—particularly when the earth is viewedfrom space; the earth always appears as a circlesince it is round.Another verse that indicates the sphericalnature of our planet is Job 26:10. Walking around on the planet's surface, it looks andfeels flat, so they deem all evidence to the contrary, such as satellite photos of Earth as a sphere, to be fabrications of a "round Earth conspiracy" orchestrated by NASA and other government agencies. The term planet is ancient, with ties to history, … ), ( After a while it has enough stuff to have a good am… 26 Best Breakup Songs Of All Time. Ceres , a round … 2 We would suffer from asteroid impacts every day. 26 Our earth is not really ‘round’, it is a shape called an ‘ellipsoid’ which is kind of squatty and fat. 9 This is a great craft to do with your kids. ), ( 20 After a while it has enough stuff to have a good amount of gravity. They are different distances from the sun. I am thirsty. However, the earth has a big pull on you. ). They are nearly perfect spheres, like marbles. We are the planets of the Solar System Different sizes for every one The music never ends We are such good friends And we all orbit the sun Here comes the Sun rapping first on this track, from the beginning I'm the center of the solar system, planets be spinning Around me, so hot, I'm roasting, ya' see? The Moon, as we can all see when we look up, is also round. ), ( Our solar system revolves around the sun, hence the name solar system. Members of the Flat Earth Society claim to believe the Earth is flat. r = J0( 1 + J1/J0 P1 + J2/J0 P2) Where, for the earth, J0 = 6368 km, J1 = 0 and J2/J0 = 0.003% You gotta check out. 8 Move your arms in and out and feel the difference. When your arms are outstretched, your hands have to move faster than your shoulders to keep up, so you'll feel more force on them. A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and – according to the International Astronomical Union but not all planetary scientists – has cleared its neighbouring region of planetesimals.. Why does that happen? The Sun is about 4.5 billion years old. ), ( The eight planets in our solar system differ in lots of ways. 5 The earth … The Nine Planets has been online since 1994 and was one of the first multimedia websites that appeared on the World Wide Web. ), ( Let's explore the rest of the Milky Way Galaxy. In our system, we have 4 terrestrial planets, 4 gas giants, and a mysterious 9th planet. Hold your arms close to your body, then extend your arms out. ( It uses its gravity to snag bits of space stuff. We are the planets big and round watch us happily fly around . 11 23 Gravity pulls from the center to the edges like the spokes of a bicycle wheel. We are the planets big and round Watch us happily fly around We are the planets big and round Watch us happily fly around I'm the largest planet I'm Jupiter Jupiter I'm the planet with the Rings I'm Saturn Saturn I have 27 moons! Instead of being perfectly round like marbles, they are like basketballs squished down while someone sits on them. They are different sizes. ), ( They are different sizes. Saturn and Jupiter are bit thicker in the middle. That is, if we had lived at a very different time, perhaps we would not see big rings around Saturn, but another one of the gas giants. From an average distance of 67 million miles (108 million kilometers), Venus is 0.7 astronomical units away from the Sun. ), ( If the Earth is round like a ball, why aren't we standing at odd ... you do not affect its motion at all. – Michio Kaku. 7 3 4 Why is that? That's why they bulge in the middle. ), ( Aristotle's reasoning is explained. So we have every reason to believe that these are indeed real planets that God created. Neptune is 1.7% thicker. 3 36 You cannot see the difference from a spherical shape for this small of an equatorial bulge. 10 If we divide every term by the radius we get: where J0 = 6368 km, J1 = 0 km, and J2 = 21 km. ), ( This is true for anything that spins, like a wheel, a DVD, or a fan. The answer has to do with how gravity works and how star systems are … 1 The Bible indicatesthat the earth isround. Why aren't they shaped like cubes, pyramids, or discs? A planet is round because of gravity. CNN studios would probably be a gigantic crater it if wasn’t for Jupiter. 20 Well, we are done exploring the Solar System. But some planets aren't quite so perfectly round. ALL PLANETS We're the planets in the Solar System Different sizes for every one The music never ends We are such good friends And we all orbit the sun. The most prominent and most famous planetary rings in the Solar System are those around Saturn, but … We round it up to a full 24 hours. A sketch of what the solar system around Proxima Centauri might look like. It is a fact that we have a ‘pudgy’ planet. ), ( As for Uranus and Neptune, they're in between. When something spins, like a planet as it rotates, things on the outer edge have to move faster than things on the inside to keep up. But looks can be deceiving. But they're all nice and round. 13 ESO/M. ), ( For instance, some of the moons around Jupiter are not very big and are not round — sort of oblong and irregular. Of course a planet is not perfectly round — look at the mountains and valleys on the Earth and on Mars! They are different distances from the sun. The Sun is so big it takes up 99% of the matter in our solar system. Tiny planets may not be very round. There is a really neat internet program called Solar System Live that shows the position of all of the planets and the Sun for any given day. 72 This is so big it is hard to imagine, but it would take more than one million Earths to fill the size of the Sun! The planets today shows you where the planets are now as a live display - a free online orrery. ), ( Some are small and rocky, and others are big and gassy. The growing planets were like big solar system vacuum cleaners, sweeping up all the debris in their paths. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.

Earth is 0.3% thicker in the middle, and Mars is 0.6% thicker in the middle. ), ( This makes the overall shape of a planet a sphere, which is a three-dimensional circle. We call the extra width the equatorial bulge. They're not perfectly round, but they're pretty close. ), ( Everyone knows that We are the planets big and round Watch us happily fly around We are the planets big and round Watch us happily fly around I'm the largest planet I'm Jupiter Jupiter I'm the planet with the Rings I'm Saturn Saturn I have 27 moons! With a radius of 3,760 miles (6,052 kilometers), Venus is roughly the same size as Earth — just slightly smaller. Do you want to know what it's like to be a spinning planet? Why are the planets round? And that can be broken down into 24 hours of 60 minutes in length which can also be divided into 60 seconds in every minute. 4 And they became round because gravity pulls equally toward the center of large masses such as planets, so anything sticking out gets pulled back to make a ball. ), ( If you compare the diameter from pole to pole to the diameter along the equator, it's not the same. Papier Mache Planets: Here are my DIY tips for creating the papier mache planets. These extrasolar planets are actually a problem for big-bang evolutionary models of solar system formation. A ring system is a disc or ring orbiting an astronomical object that is composed of solid material such as dust and moonlets, and is a common component of satellite systems around giant planets. Rings around gas giants are thought to be transient over the the lifetime of the planetary system. You can feel it when you spin around in place. It takes sunlight 6 minutes to travel from the Sun to Venus. That's the force that holds stuff together in space. A look at the evidence for the Earth being round or spherical. For that matter, why are all the big objects in the Universe this shape? The 1% left over is taken up by planets, asteroids, moons and other matter. Here are seven other ways to prove our planet is spherical. Rapper B.o.B wants to launch a satellite into space to find out, once and for all, whether the Earth is flat or round. Orbit and Rotation Keep in mind that this … Kornmesser. Mercury and Venus are the roundest of all. ), ( IntroductionThis seemingly simple question doesn't have a simple answer.
