Mercury attains an inferior conjunction (nearest approach to Earth) every 116 Earth days on average, [4] but this interval can range from 105 days to 129 days due to the planet's eccentric orbit. Mercury can come as near as 82,200,000 km (0.549 astronomical units; 51.1 million miles) to Earth, and that is slowly declining: The next approach to ...
A spacecraft has beamed back some of the best close-up photos ever of Mercury’s north pole. The European and Japanese robotic explorer swooped as close as 183 miles (295 kilometers) above ...

Reprocessed Mariner 10 data was used to produce this image of Mercury. The smooth band is an area of which no images were taken. Mariner 10 was an American robotic space probe launched by NASA on 3 November 1973, to fly by the planets Mercury and Venus.
Caravaggio is an example of a Peak ring impact basin on Mercury. Several areas on Mercury are extremely dark, such as a small crater within Hemingway crater in the lower right. The geology of Mercury is the scientific study of the surface, crust, and interior of the planet Mercury. It emphasizes the composition, structure, history, and physical ...
The surface of the planet Mercury has been divided into fifteen quadrangles, designated H-1 to H-15 (the 'H' stands for Hermes, the Greek equivalent of Mercury). [1] The quadrangles are named for prominent surface features visible within each area. [1]
In many cases it is not possible to have an exact value, and an estimated range is instead provided. The coldest and oldest planet directly imaged is Epsilon Indi Ab, which has six times Jupiter's mass, an effective temperature of 275 K, and an age of about 3.5 Ga. This list includes the four members of the multi-planet system that orbit HR 8799.
