In order to leave the Solar System, the probe needs to reach the local escape velocity. Escape velocity from the sun without the influence of Earth is 42.1 km/s. In order to reach this speed, it is highly advantageous to use as a boost the orbital speed of the Earth around the Sun, which is 29.78 km/s.
It communicates through the NASA Deep Space Network (DSN) to receive routine commands and to transmit data to Earth. Real-time distance and velocity data are provided by NASA and JPL. [4] At a distance of 166.28 AU (24.9 billion km; 15.5 billion mi) from Earth as of December 2024, [4] it is the most distant human-made object from Earth. [5]
It is currently the furthest man-made object from Earth, as well as the first object to leave the heliosphere and cross into interstellar space. As of November 2017 it has a distance from the Sun of about 140 astronomical units (AU) [ 10 ] (21 billion kilometers, or 0.002 light years), and it will not be overtaken by any other current craft.
Artificial satellites and space probes in the 1970s Year Origin Name Target Status Description 1970 Japan: Ohsumi: Earth: Success: First Japanese satellite. Japan became the fourth nation after the USSR, USA and France to successfully put an artificial satellite into orbit on its own. West Germany: DIAL Earth Success Second German satellite.
Scientists are set to create an artificial solar eclipse by launching synchronised satellites into space.. The Proba-3 mission is the world’s first precision formation flying mission, requiring ...
In the Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris. Moons by contrast are not in a heliocentric orbit but rather orbit their parent object. Geocentric orbit: An orbit around the planet Earth, such as that of the Moon or of artificial satellites.
The first artificial satellite launched into the Earth's orbit was the Soviet Union's Sputnik 1, on October 4, 1957. As of December 31, 2022, there are 6,718 operational satellites in the Earth's orbit, of which 4,529 belong to the United States (3,996 commercial), 590 belong to China, 174 belong to Russia, and 1,425 belong to other nations.

It therefore is an artificial satellite featuring habitation facilities. The purpose of maintaining a space station varies depending on the program. Most often space stations have been research stations, but they have also served military or commercial uses, such as hosting space tourists.
