What asteroid in the Asteroid Belt is named after Alexander Fleming?

The asteroid in the Asteroid Belt named after Alexander Fleming is 91006 Fleming.

91006 Fleming is a main-belt asteroid, the broad region between the orbits of Mars and Jupiter where most known asteroids travel. Its provisional designation was 1998 BT25, reflecting its discovery in 1998 before it received a permanent number and name.

Czech astronomers Miloš Tichý and Zdeněk Moravec discovered the object on 28 January 1998 at Kleť Observatory. The International Astronomical Union approved the name Fleming in 2007, commemorating the Scottish bacteriologist and pharmacologist whose work led to the discovery of penicillin.

The name can cause a small trivia mix-up: Fleming is also associated with a lunar crater, and another minor planet, 91007 Ianfleming, honours the novelist Ian Fleming. The number 91006 specifically identifies the asteroid named for Alexander Fleming.
