Venus because they both have no moons
mercury is very very heater than other planets
No, Mercury does not have a twin planet. It is the smallest and innermost planet in our solar system, and there is no other planet that is exactly like Mercury in terms of its size, composition, and distance from the Sun.
Mercury is a rocky planet. The inner planets (first four planets from the sun) are rocky planets (which means that you could stand on them) and are the smallest. While the outer planets (last four planets from the sun) are gas planets and the biggest.
Mercury is the smallest planet compared to the other ones
well it is the first planet so they had to make it before the other planets am i right lol
pretty much all the other planets
It's Venus, not Mercury. Mercury spins slowly, but not in a retrograde rotation. Venus spins the opposite way from the other planets, except for one of the outer planets (Uranus).
It is the second smallest of the 8 planets, only larger than Mercury.
No. Our planet (Earth) is made up of 1 planet.
Mercury is not the coldest planet because it has more solar radiation than all of the other planets. This is because it is closer to the Sun. However, Mercury is not the hottest planet in the Solar System. See related question.
Earth is a terrestrial planet. The three other terrestrial planets are Mercury, Venus, and Mars.
The planets are either inner or outer planets. There are 8 planets. And of those eight planets: Mercury, Venus, Earth, and Mars are the inner planets. While: Jupiter, Saturn, Uranus, and Neptune are the outer planets.
