Potential planet found orbiting a dead star
Today’s Video of the Day from NASA Goddard describes the first possible example of an intact planet closely orbiting a small dead star.
NASA’s Transiting Exoplanet Survey Satellite (TESS) and the retired Spitzer Space Telescope detected a large object that appears to be a giant gaseous planet. The data also reveals the presence of a smaller object that looks like a white dwarf – a dead star that has burned up all of its nuclear fuel.
The potential planet, known as WD 1856 b, is about seven times larger than the white dwarf, which it circles every 34 hours. The scientists estimate that the planet has about 14 times the mass of Jupiter.
