First possible 'survivor' planet found orbiting white dwarf star

Using data from NASA missions, an international team of astronomers has found what may be the first intact planet orbiting a white dwarf, the dense leftover of a Sun-like star, only 40 per cent larger than Earth. The Jupiter-size object, called WD 1856 b, is about seven times larger than the white dwarf, named WD 1856+534. It circles this stellar cinder every 34 hours, more than 60 times faster than Mercury orbits our Sun.
