What is the rank of planet Earth?
The second planet in the solar system, Venus, is the third smallest planet with a radius of 3761 miles (6052 km). Earth, of course, is the third closest planet to the Sun and the fourth smallest with a radius of 3963 miles (6378 km). Just past Earth is Mars, the fourth planet in the solar system.
What size is the Earth compared to other planets?
It’s smaller than the four gas giants — Jupiter, Saturn, Uranus and Neptune — but larger than the three other rocky planets, Mercury, Mars and Venus. Earth has a diameter of roughly 8,000 miles (13,000 kilometers) and is mostly round because gravity generally pulls matter into a ball.
What’s the smallest planet?
Mercury

How is Earth similar to planets?
Earth does rotate in its orbit, so it has a day and night cycle. It can also be seen that Earth can, in fact, support human life, and all known carbon-based life for that matter. Mars has a solid, rocky surface, so there is a ground. The atmosphere there is thin, meaning there is a sky.
Why are planets different sizes?
CONSTRUCTAL LAW AND PLANETS But if a system, such as our solar system, had a few large bodies and a greater number of smaller ones, the tension would reduce quickly. The simple action of gravity explains why planets, stars and other bodies grow larger, because more massive bodies attract smaller objects to them.
Is Jupiter bigger than the moon?
How big is the Moon? Our Moon has a mean radius of 1,737 kilometers / 1,079 miles, while its polar radius is 1,736 km / 1,078 mi, and its equatorial radius is 1,738 km / 1,079 mi….

Why is Mars red?
Well, a lot of rocks on Mars are full of iron, and when they’re exposed to the great outdoors, they ‘oxidize’ and turn reddish – the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.
Can we visit other planets?
In short, a visit to another planet by a human crew is possible, but some are easier to explore than others. Each planet is different and has a unique set of challenges. For example, the largest planet in our Solar System, Jupiter, is a ‘gas giant’ mainly composed of hydrogen and helium gas.
Why are some planets bigger than other planets?
Since the planets were closer to the sun, the heat made the gases go away. They’re also huge planets because it is easier compared to the smaller planets to gain mass since the bigger it is, the more gravity it has, which makes it easier to pull in gas, which is what the larger planets are made out of.

What is the largest planet in the Solar System?
Jupiter – 43,441mi (69,911km) radius; 11x Earth’s size Saturn – 36,184mi (58,232km) radius; 9x larger than Earth Uranus – 15,759mi (25,362km) radius; 4x Earth’s size
What is the correct order of the planets in the Solar System?
Planets In Order: By Size And Distance From The Sun. The planets in order from the sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and finally the dwarf planet Pluto. Most people have at least heard about our solar system and the planets in it.
How many planets are there in the Solar System?
Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, followed by the dwarf planet Pluto. Jupiter’s diameter is about 11 times that of the Earth’s and the Sun’s diameter is about 10 times Jupiter’s.
