Mercury, Venus, Earth, and Mars are called the inner planets.
Mercury and Venus have no known satellites, all other planets have at least one.
They are classified as terrestrial planets. The other grouping is called the gas giant planets.
Neptune and Mercury are the two planets farthest apart from each other in terms of distance in our solar system.
One way Mercury and Venus are the same in which they differ from other planets is that they are both very hot and dry in the daytime
Mercury is the closest planet to the Sun and is smaller and has a thinner atmosphere than Venus. Venus, on the other hand, is similar in size to Earth but has a thick, toxic atmosphere that traps heat, making it the hottest planet in the solar system. Both planets have no moons and have extreme temperatures, but Venus has a slower rotation and rotates in the opposite direction to most other planets.

Mercury came from the same Solar nebula that the Sun, Earth and the other planets came from.
