Mercury orbits the Sun closer than Earth; as a result, from our point of view, its angular distance from the Sun can never be more than about 28 degrees.
Earth is the third planet from the sun, after Mercury and Venus.
Mercury is located closest to the Sun in our solar system. Its position from Earth varies as both planets orbit the Sun. Mercury can be found in the sky either to the east or west of the Sun depending on its position in its orbit.
Earth is number 3.

Mercury rotates once in about 58.6 Earth days. That's one definition of its day. However, Mercury's "solar day" lasts about 176 Earth days. That "day" is based on the position of the Sun in the sky. It depends on Mercury's orbital motion as well as its rotation on its axis.
It is the 7th furthest planet after Mercury, Venus, Earth, Mars, Jupiter and Saturn.
SOLAR SYSTEM: Sun - Mercury - Venus - Earth - Mars - Jupiter - Saturn, Uranus... and so on
Mercury's diameter is about a third that of Earth.
By the Earth's gravity. This is why celestial bodies like the Moon and Mercury do not have atmospheres, they don't have enough gravity to hold onto the gases.
Mercury's gravity is 38% of that on Earth.
