In the diagram, the varying distance of Mercury to the Sun is represented by the size of the planet, which is inversely proportional to Mercury's distance from the Sun. This varying distance to the Sun leads to Mercury's surface being flexed by tidal bulges raised by the Sun that are about 17 times stronger than the Moon's on Earth. [110]
Mercury: 0.39 – Average distance from the Sun – Venus: 0.72 – Average distance from the Sun – Earth: 1.00 – Average distance of Earth's orbit from the Sun (sunlight travels for 8 minutes and 19 seconds before reaching Earth) – Mars: 1.52 – Average distance from the Sun – Jupiter: 5.2 – Average distance from the Sun – Light ...

A lunar eclipse as viewed from Mercury, captured from the MESSENGER spacecraft. The Moon can be seen falling into the shadow of Earth. The Earth and the Moon also will be very bright, their apparent magnitudes being about −5 [3] and −1.2, respectively. The maximum apparent distance between the Earth and the Moon is about 15′.
Earth at seasonal points in its orbit (not to scale) Earth orbit (yellow) compared to a circle (gray) Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi), or 8.317 light-minutes, [1] in a counterclockwise direction as viewed from above the Northern Hemisphere.
This diagram shows various possible elongations (ε), each of which is the angular distance between a planet and the Sun from Earth's perspective. In astronomy, a planet's elongation is the angular separation between the Sun and the planet, with Earth as the reference point. [1] The greatest elongation is the maximum angular separation.
The average date for a transit increases over centuries as a result of Mercury's nodal precession and Earth's axial precession. Transits of Mercury occur on a regular basis. As explained in 1882 by Newcomb, [ 8 ] : 477–487 the interval between passages of Mercury through the ascending node of its orbit is 87.969 days, and the interval between ...
