1580 Betulia (provisional designation: 1950 KA) is an Amor asteroid discovered on May 22, 1950, by Ernest Leonard Johnson at the Union Observatory, Johannesburg, South Africa. Betulia's shape has been accurately determined: at its widest point, the asteroid is 6.59 ± .66 km wide; however, its effective diameter is 5.39 ± .54 km.
The name honours Betulia Toro, wife of the astronomer Samuel Herrick. Herrick had studied the asteroid's orbit, and requested the name, along with that of 1685 Toro.
