Because Mercury is nearest to the sun, which gives more heat and gravitational pull. It is also the smallest and second-densest and has the greatest day and night temperature variations. It also has the oldest surface. Besides earth, it is the only terrestrial (rock like; not a gas planet) planet that has a global internal magnetic field.
hottest planet
mercury is very very heater than other planets
Neptune and Mercury are the two planets farthest apart from each other in terms of distance in our solar system.
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.
Venus because they both have no moons
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.
