3000 Leonardo

3000 Leonardo, provisional designation 1981 EG₁₉, is a carbonaceous background

Leonardo is a non-

In 1986, 3000 Leonardo was observed to be at its predicted location.[15] It was one of 450 minor planets whose location was checked in a large observation campaign involving multiple sites and astronomers.^[15] 3000 Leonard was visually observed by Roger E. Harvey on August 30, 1986 with a 73 cm Newtonian telescope from eastern North America (Concord, North Carolina in the United States).^[15][16]

The sequence continues with the asteroids

By 2001, 3000 Leonardo was one of 32 named minor planets named after painters and sculptors, and some other examples in this category include

At the time of 3000 Leonardo's discovery and naming only a few thousand asteroids had been discovered and named, it would not be until the 1990s and early 2000s when there was a massive spike in asteroid discoveries, with the peak year up to the year 2010, being 2000.[22] In the year 2000, over 40,000 minor planets were recorded, and in the years after many tens of thousands were discovered leading to almost 220,000 numbered minor planets by late 2009.^[22]

Physical characteristics

Leonardo was one of 1341 main-belt asteroids observed between 1993 and 1999 as part of

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a stony asteroid of 0.20 (rather than for a carbonaceous one) and consequently calculates a shorter diameter of 5.41 kilometers based on an absolute magnitude of 13.7.^[13]
