2019 van Albada, provisional designation 1935 SX1, is a main-belt asteroid discovered on September 28, 1935 by Dutch astronomer Hendrik van Gent at Leiden Southern Station, annex to the Johannesburg Observatory in South Africa. It is a S-type asteroid.[1]
The asteroid was considered as a flyby target of the NEAR unmanned robotic spacecraft mission in the 1990s.[3] NEAR eventually launched, but visited 253 Mathilde and 433 Eros.
It was named in memory of Dutch astronomer Gale Bruno van Albada (1911–1972), who was director of the Bosscha Observatory and of the Astronomical Institute at Amsterdam.[2]
