After seeing this tweet by astronomer Kacper Wierzchoś about our not-so-new but at least newly-discovered "mini-moon" I scrolled down and saw the tweeted image below.

The object is the known short-period comet 114P/Wiseman–Skiff. The article goes on to say:

Comet 114P/Wiseman–Skiff is believed to have been the parent body of the first meteor photographed from Mars


and that article says

As on Earth, when a meteor is large enough to actually impact with the surface (without burning up completely in the atmosphere), it becomes a meteorite. The first known meteorite discovered on Mars (and the third known meteorite found someplace other than Earth) was Heat Shield Rock. The first and the second ones were found on the moon by the Apollo missions.

This doesn't mention Egg Rock (as discussed in Who discovered “Egg Rock”? The Curiosity rover or people?) so we know that there must be at least four meteorites found some place other than Earth.

But I don't yet know how many there are in total

Question: How many meteorites have been found some place other than Earth? Where is an authoritative tally or listing actively maintained?

  • $\begingroup$ Mars, impact craters found on Venus (possible explanation as Venus atmosphere is so dense, they break up creating clusters and craters. $\endgroup$ – Nilay Ghosh Nov 6 '20 at 8:52
  • $\begingroup$ Statistically, if they found a basketball meteorite, they could have passed 50 golfball ones and 1000 pea sized ones. Check "tour of moon in 4k" one crater has a 100m rock on the central mound. $\endgroup$ – aliential Dec 28 '20 at 3:01
