This hot jupiter is doomed. Hot jupiters are
giant planets like Jupiter that
orbit much closer to their parent stars than Mercury does
to our Sun. But
some hot jupiters are
more extreme than others. NGTS-10b, illustrated
generically, is the closest and fastest-orbiting giant planet yet
discovered, circling its home star in only 18 hours. NGTS-10b is
a little larger than Jupiter, but
it orbits less than two times the diameter of its parent star away from the
star’s surface. When a planet orbits
this close, it is expected to spiral inward,
pulled down by tidal forces to
be eventually ripped apart by the star’s gravity. NGTS-10b,
discovered by researchers at the University of Warwick, is
named after the ESO’s Next Generation Transit Survey,
which detected the imperiled planet when it passed in front of its star, blocking some
of the light. Although the violent demise of
NGTS-10b will happen eventually, we don’t yet know when.
