The probe left the heliosphere for interstellar space at 119 AU on November 5, 2018. [4] Voyager 2 is still active. It is not heading toward any particular star, although in roughly 40,000 years it should pass 1.7 light-years from the star Ross 248. [5] Ross 248 and the Sun currently approach each other.
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.
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.
The target satellite orbited between 850 km (530 mi) and 882 km (548 mi), the portion of near-Earth space most densely populated with satellites. [98] Since atmospheric drag is low at that altitude, the debris is slow to return to Earth, and in June 2007 NASA's Terra environmental spacecraft maneuvered to avoid impact from the debris. [99]
The International Space Station, as seen by a visiting spacecraft in 2021. This article is a list of accidents and incidents related to the International Space Station (ISS). It includes mishaps occurring on board the ISS, flights to and from the space station, as well as other program related incidents.
They found shifts about 100,000 years before the asteroids hit, but none around the time of the impacts or afterwards. A microscopic image shows the silica droplets that were found in a rock core.
There are 1620 near-Earth asteroids listed in the risk table and 37,736 virtual impact dates, so for each asteroid in the risk table, there is an average of about 23 virtual impact dates. Only about 19 objects in the table are large enough, with a diameter greater than about 140 meters, to be considered potentially hazardous objects .
The 2002 Eastern Mediterranean event and the Chelyabinsk meteor (Russia, February 2013) were not detected in advance by any Spaceguard effort. On October 6, 2008, the 4-meter 2008 TC 3 meteoroid was detected by the Catalina Sky Survey (CSS) 1.5 meter telescope at Mount Lemmon, and monitored until it hit the Earth the next day.
