Tea[4] (minor planet designation: 453 Tea) is an S-type asteroid[5] belonging to the Flora family in the Main Belt.[3] Its diameter is about 21 km and it has an albedo of 0.183.[6] Its rotation period is 6.4 hours.[7]
In the 1980s Tea was considered as a target for the planned French Vesta spacecraft.[8] The spacecraft was not built.
Tea was discovered by Auguste Charlois on February 22, 1900. Its provisional name was 1900 FA. It is unknown after what it was named.[9]
It came to opposition at apparent magnitude 12.2 on 3 May 2023 and then perihelion on 27 May 2023.[2]
