What is the name of the asteroid named after John Lennon?

The asteroid named after John Lennon is 4147 Lennon. Its official minor-planet designation is (4147) Lennon, so the stored answer gives the standard numbered name used by astronomers and reference works.

4147 Lennon was discovered by American astronomer Brian A. Skiff on 12 January 1983 at Lowell Observatory’s Anderson Mesa Station in Arizona. It belongs to the inner asteroid belt and is associated with the Vesta family, whose namesake is the large asteroid 4 Vesta.

The asteroid is roughly 7 kilometres across and takes about 1,326 days—approximately 3.63 years—to orbit the Sun. Its name commemorates Lennon, the Beatles co-founder and songwriter who died in 1980.

A common mix-up comes from the related Beatles-themed asteroid names. 4148 McCartney, 4149 Harrison and 4150 Starr were also named for Beatles members, while 8749 Beatles commemorates the band itself. Thus, “4147 Lennon” is not merely a descriptive nickname; it is the specific numbered asteroid name.
