This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
A geocentric orbit, Earth-centered orbit, or Earth orbit involves any object orbiting Earth, such as the Moon or artificial satellites. In 1997, NASA estimated there were approximately 2,465 artificial satellite payloads orbiting Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center . [ 1 ]
Earth will have a 'mini-moon' for nearly 2 months starting Sunday, researchers say. ... Science identified two other "orbiters” in 2006 and 2020 as well as two other “flybys” in 1991 and 2022.
Geosynchronous orbit (GSO): An orbit around the Earth with a period equal to one sidereal day, which is Earth's average rotational period of 23 hours, 56 minutes, 4.091 seconds. For a nearly circular orbit, this implies an altitude of approximately 35,786 kilometers (22,236 mi). The orbit's inclination and eccentricity may not necessarily be zero.
This is a list of all spacecraft landings on other planets and bodies in the Solar System, including soft landings and both intended and unintended hard impacts.The list includes orbiters that were intentionally crashed, but not orbiters which later crashed in an unplanned manner due to orbital decay.
Once the MTM delivers the MPO and MMO to Mercury orbit, the two orbiters will have the following objectives: to study Mercury's form, interior structure, geology, composition, and craters; to study the origin, structure, and dynamics of its magnetic field; to characterize the composition and dynamics of Mercury's vestigial atmosphere; to test ...
The following table is a list of Mars orbiters, consisting of space probes which were launched from Earth and are currently orbiting Mars. As of August 2023, there have been 18 spacecraft missions operating in Mars' orbit, 7 of which are currently active.
