White Dwarf ZTF J1901+1458

Caption

This illustration highlights a newfound small white dwarf, discovered by ZTF, that is 4,300 kilometers across, or roughly the size of Earth's moon, which is 3,500 kilometers across. The two bodies are shown next to each other for size comparison. The hot, young white dwarf is also the most massive white dwarf known, weighing 1.35 times as much as our sun.
