The answer will depend on ratio of which characteristic. Each of the following will have a different ratio:radius, surface area, volume, mass, density, surface gravity, average distance from the Sun, perihelion, aphelion, orbital period, orbital eccentricity, rotational period, atmospheric pressure, albedo. And there are many more besides. Without some focus, this question is a complete waste of time.
Mass ratio = 1 : 18.09
Inner planet
mercury and venus
Mercury is the closest planet to the Sun and has one planet[venus] between us[Earth] and Mercury.
Mercury is closer to the earth than the sun is, because the orbit of Mercury is between the sun and the orbit of Earth. However, when Mercury is on the opposite side of the sun from the earth, the sun is closer to the earth than Mercury is.
Mass ratio = 1 : 18.09
The orbits of Mercury and Venus are between the sun and the orbit of Earth. That is different from saying that Mercury and Venus are between the sun and Earth, which is often not true.
Mercury and venus
There are no stars between the earth and the moon. ** If there were, Earth would be as barren and lifeless as Mercury.
Inner planet
mercury and venus
Two, Mercury and Venus.2, mercury and venus
Mercury is the closest planet to the Sun and has one planet[venus] between us[Earth] and Mercury.
Mercury is closer to the earth than the sun is, because the orbit of Mercury is between the sun and the orbit of Earth. However, when Mercury is on the opposite side of the sun from the earth, the sun is closer to the earth than Mercury is.
All the theories have Mercury and Venus between the Earth and the Sun.
Currently October 08 no planets are between Mars and Venus. Two planets can pass between them Mercury and Earth although in the case of Mercury Venus and Mars will also have the Sun between or nearly between them.Earth!!!!!!!!
Earth is about 18.2 times more massive than mercury.
