Inferior, as its orbit is closer to the Sun
that they were inferiour to men.
The farthest distance between Earth and Mercury is when they are on opposite sides of the Sun, which can be up to 221 million kilometers (137 million miles) apart. This phenomenon is known as superior conjunction.
The terms "inferior planet" and "superior planet" were originally used in the geocentric cosmology of Claudius Ptolemy to differentiate those planets (Mercury and Venus) that were between the stationary Earth and the orbiting Sun from those planets (Mars, Jupiter, and Saturn), which lay beyond the Sun's orbit.The terms are now used with the heliocentric model."Inferior Planets" have orbits closer to the Sun than the Earth's orbit.They are Mercury and Venus.The "Superior Planets" have orbits outside the Earth's orbit.They are Mars,Jupiter, Saturn, Uranus and Neptune.So, the meaning is slightly different from "Inner Planets" and "Outer Planets".
An celestial body is at superior conjunction if it is on the opposite side of the sun from the Earth. A celestial body is at inferior conjunction when it is between the sun and the Earth. _______________________________________Only interior planets (Mercury and Venus) can have "superior conjunctions". The outer planets Mars, Jupiter and Saturn have either "conjunctions" (when the planet is on the other side of the Sun) or "opposition" (when the planet is opposite the Sun in the sky.
Yes. The inferior planets not only move faster, but also have a smaller path, to go once around the Sun. So, both of these factors contribute for the interior planets to take less time to go once around the Sun.
Mercury's diameter is about a third that of Earth.
Mercury is 57.9x106km from Earth.
mercury is smaller then earth
Mercury's gravity is 38% of that on Earth.
Earth > Venus > Mercury > Mars
Earth has 2.54 times the surface area of Mercury. Earth-12,756 km Mercury-4,880 km
The gravity on Mercury is 38% of Earth's gravity. So, if you were 150mlbs on Earth, you would be 57 lbs on Mercury.
