1058 Grubba, provisional designation 1925 MA, is a stony Flora asteroid from the inner regions of the asteroid belt. It was discovered on 22 June 1925, by Soviet–Russian astronomer Grigory Shajn at the Simeiz Observatory on the Crimean peninsula.^[1] The S-type asteroid was named for Irish telescope maker Howard Grubb.^[2] It has a longer-than average rotation period of 46.30 hours and measures approximately 12 kilometers (7.5 miles) in diameter.^[4]
