The scale bar is in astronomical units, with each set distance beyond 1 AU representing 10 times the previous distance. One AU is the distance from the sun to the Earth, which is about 93 million miles or 150 million kilometers. Neptune, the most distant planet from the sun, is about ...
Two decades before it notched that milestone, however, Voyager 1 took one of the most iconic photos in spaceflight history. On Feb. 14, 1990, the probe turned back toward Earth and snapped an image of its home planet from 3.7 billion miles (6 billion km) away. The photo shows Earth as...
Theory predicts that a termination shock marks this boundary, with locations ranging from a few to over 100 au (1 Au approximately 1.5 x 10(8) km, the distance from Earth to the Sun). 'Pick-up ions' that originate as interstellar neutral atoms should be accelerated to tens of MeV at ...
6、On Aug. 15, NASA's enduring Voyager 1, already Earth's farthest-flung robotic ambassador, became the first spacecraft to reach a distance of 100 astronomical units (AU) from the Sun.───在8月15日,美国国家航天局的旅行者一号,已经是地球的最遥远的机器人大使。成为第一架抵达距太阳100个...
The heliopause remains an unknown distance ahead. On December 10, 2007, instruments on board Voyager 2 sent data back to Earth indicating that the solar system is asymmetrical. It has also reached the termination shock, about 10 billion miles from where Voyager 1 first crossed it, and is ...

Heliospheric magnetic field strength out to 66 AU: Voyager 1, 1978-1996 We discuss Voyager 1 (V1) observations of the heliospheric magnetic field strength from 1978 through 1996. During this period the distance of V1 from the S... LF Burlaga,NF Ness,YM Wang,... - 《Journal of Geophysi...
That might sound like a long way out, but on cosmic scales it missed by a whisker – it’s closer than theVoyager probes, which are more than 136 times the Earth-Sun distance (Astronomical Units, or AU). The previousclosest known passwas Scholz’s Star, which swept past at more than...
- both moons occupy the same orbit and keep swapping places every four years) at a few thousand kilometres distance. The moons had been tentatively discovered from earth but the fact that there were actually two of them caused confusion which was not properly resolved until Voyager 1 in 1980....
Voyager, either of a pair of robotic U.S. interplanetary probes launched to observe and to transmit information to Earth about the giant planets of the outer solar system and the farthest reaches of the Sun’s sphere of influence. Voyager 1 and 2 were th
