| You can place more than six Mars-sized planets on earth. The largest planet in our solar system, the size of Jupiter, is amazing. Jupiter has a volume of 1.43 x 1015 cubic kilometers. To show what this number means, you can place 1321 lands in Jupiter.
Mars is smaller than Earth, while Jupiter is so large that it can hold over 1,000 Earths.
The diameter of Mercury is 4,879.4 km and that of Jupiter 142,984 km. In other words, Jupiter is 29.3 times larger than Mercury. In terms of volume, 24,462 Mercury enters Jupiter.
The volume of Mars of 1.63 x 1011 km3 corresponds to only 15% of the volume of the earth. All gas giants are larger than the four inner planets. Jupiter is the largest planet in our solar system. It has a diameter of 143,000 km, more than 11 times the diameter of the earth.
The temperature in Jupiter’s clouds is about minus 145 degrees Celsius (minus 234 degrees Fahrenheit). The temperature near the center of the planet is much, much warmer. The internal temperature can be around 24,000 degrees Celsius (43,000 degrees Fahrenheit). It is hotter than the surface of the sun!
The problem is that we can’t travel at the speed of light, but we can travel to Jupiter on an artificial rocket. We can also send a spaceship, which is what we have done in the history of space exploration. In 1989, scientists sent a space probe to Jupiter and it took just over six years to reach the planet.
Jupiter has been called a failed star because it is made up of the same elements (hydrogen and helium) as the sun, but it is not massive enough to have the internal pressure and temperature needed to fuse hydrogen, helium, the energy source that hovers the sun and most of the other stars.
Saturn has 62 confirmed moons, 9 of which are awaiting an official name. Saturn’s largest moon, Titan, is larger than Mercury and Pluto. Titan has a very dense atmosphere, consisting mainly of nitrogen. The earth’s atmosphere is also made up to a large extent of nitrogen.
Scientists have successfully tracked the wind in the atmosphere of a planet orbiting a star in the constellation of Pegasus. The windiest planet in our solar system is Neptune with a speed of 1,200 miles per hour.
61.42 billion km²
The second planet in the solar system, Venus is the third smallest planet with a radius of 6,052 km.
The great Jupiter is composed mainly of hydrogen and helium and looks like a small star. But even though the gas giant is the largest planet in the solar system, it doesn’t have the mass to make it a star.
