These are part of a larger structure called the Milky Way, which consists of every star we can see, plus many more that are too far away or too faint for our eyes to see. From an area on Earth with a very dark sky, we can see about 6 000 other stars, and each of these stars has its own planetary system of objects like planets, asteroids, and comets. If we look outside the solar system, we see many other stars like the Sun. The Sun and everything that orbits it are known collectively as the solar system. Besides Earth, there are seven other planets orbiting the Sun, as well as a host of other objects including moons, comets, and asteroids. We live on planet Earth, which orbits the Sun. It is merely a theory, but it’s fascinating nonetheless.In this explainer, we will learn how the universe began and how it has changed over the course of billions of years.īefore we talk about its origins, we first need to understand what we mean by “the universe.” There is a theory that this planet is massive and at one point had a collision with Jupiter that “bounced” it farther away. This planet was predicted in 2014 after astronomers noticed that Neptune’s orbit was slightly different than some other planets. In the image above the bright star is representative of the sun, which is pretty dang far. Nothing is actually known about Planet Nine, just that it probably exists. We have never seen this final planet, but scientists are predicting it exists (just as they did with Neptune). The “last” planet on our list is Planet Nine. NASA sent a probe to Pluto in 2006 named New Horizons and it completed its Pluto flyby in 2015. Pluto is only 1,400 miles wide, making it smaller than the United States. Now people have petitioned to bring Pluto back to its planet-hood, but who knows if that will happen. Pluto used to be the ninth planet in our solar system but was removed in 2006 because in all the time we’ve known about Pluto is has yet to complete an orbit around the sun. 1 day is the equivalent of 18 Earth hours.1 orbit around the sun takes 84 Earth years.Uranus’ core is thought to be extremely icy, instead of being molten like other planets. The planet is made up of helium and hydrogen and is believed to have icy elements on its surface. It is believed that Uranus had a collision with another planet, causing its tilt. Uranus has a very serious tilt to where the equator is actually at a right angle to the orbit. We will never forget them, nor the last time we saw them, this morning, as they prepared for their journey and waved good-bye and ‘slipped the surly bonds of earth’ to touch the face of God. “The crew of the space shuttle Challenger honored us by the manner in which they lived their lives. Our first images of Uranus came on the same day that the Challenger blew up, killing the 7 astronauts on board. Just like Jupiter and Saturn, the Voyager probe gave us our first look at the planet in 1986. Uranus is the seventh planet from the sun and is the third of the gas giants. 1 day on Venus is the equivalent of 241 Earth days.The Soviet Union sent the probes in the Venera series to learn more about Venus that helped us learn a bit about Venus’ atmosphere, and Venera probes are actually the first manmade devices to enter another planet’s atmosphere. Venus is similar to Earth in size and general structure. Venus is actually hotter than Mercury and is abundant in greenhouse gasses. Venus is the second planet in our solar system and is named after the Roman goddess of love. Has a diameter of a little over 3,000 miles.NASA launched the MESSENGER probe in 2004 to learn all about Mercury since we don’t really know much about it. It is slightly smaller than Earth’s moon and is extremely hot. The first planet in our solar system is Mercury. Planets in order of distance from the Sun: Planet Let’s go over them, but first, here’s a quick rundown of each planet in order of size and distance from the sun. In our system, we have 4 terrestrial planets, 4 gas giants, and a mysterious 9th planet. Our solar system revolves around the sun, hence the name solar system. – Michio Kaku Our Solar System’s Planets in Order CNN studios would probably be a gigantic crater it if wasn’t for Jupiter. We would suffer from asteroid impacts every day. Without Jupiter cleaning out the early solar system, the Earth would be pock-marked with meteor collisions. Check out this guide to learn all about the planets, their size, and their order in the solar system. Our solar system is usually gone over in elementary school, so you might just need a refresher course about the planets in order in our solar system. Most people have at least heard about our solar system and the planets in it. The planets in order from the sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and finally the dwarf planet Pluto.
