The outer planets of our Solar System, upon examination, help us to really understand the sheer size of not only our own system but the whole Universe. If you are thinking about which are the four outer planets in our solar system model they are Jupiter, Saturn, Uranus, and Neptune.
The Four Solar System Models Of Planet
Solar System Model- Jupiter
As we venture out past Mars and the Asteroid Belt, we find the fifth and largest planet in our solar system, Jupiter. The largest planet in our solar system, Jupiter, is so big that over 1,000 Piles of earth could fit inside it. Jupiter comes as close as 365 million miles away from the Earth at its closest point in orbit.
That’s more than the distance from Mercury to the Earth, Venus to the Earth, and Mars to the Earth combined! Its distance from the Sun is even more remarkable: 460 million miles at its closest and 508 million miles at its farthest point in orbit. It takes Jupiter 12 Earth years to orbit the Sun and spins on its own axis every 9.8 hours. This means that Jupiter is spinning very quickly about its own axis, just short of 3 times as fast as the Earth spins. Jupiter is considerably colder than the Earth.
Saturn is the second-largest planet, located about 746 million miles away from our planet Earth. This is almost twice as far away as Jupiter is from the Earth! During its orbit around the Sun, Saturn ranges from 840 million miles to 938 million miles away from the Sun. It takes Saturn almost 30 Earth years to make it around the Sun. Like Jupiter, Saturn is spinning about its axis much faster than the Earth. Saturn takes only 10.67 Earth hours to rotate once about its axis.
Uranus marks the point where we start discussing distances in billions of miles, not millions of miles. Uranus is 1.6 billion miles away from Earth, which is a little less than twice as far away as Saturn is from the Earth. This figure alone can help us once again begin to notice the vast scope of our solar system. Uranus ranges from 1.7 billion and 1.87 billion miles away from the Sun in its orbit. Uranus takes 84 Earth years to make one revolution around the Sun.
The last recognized planet in our solar system is Neptune. Neptune is closest to our planet Earth when it is 2.68 billion miles away. Neptune’s closest distance from the Sun is 2.77 billion miles and 2.87 billion miles away from its farthest distance. That’s almost 30 times as far away from the Sun as planet Earth! While it seems that the time Uranus takes to orbit the Sun is extremely long, Neptune takes almost twice as long. It takes 165 Earth years for Neptune to make a single journey around the Sun. A day on Neptune also takes 17 hours.
As you can see, the farther we journey outward in our solar system, we can begin to see just how expansive the universe is. Our solar system orbits just one star, of billions of stars in our galaxy, which is just one galaxy out of billions of other galaxies. Learning about our outer planets is just the beginning of a multitude of areas to discover the Universe.
