Kepler-84

Kepler-84 is a Sun-like star 1118 light years (342 parsecs) from the Sun. Kepler-84 is a G-type star and a near solar twin. A speckle survey of G-dwarfs by Elliott P. Horch in 2002 noted that Kepler-84 may not be non-single star.[3]

Planetary system

Kepler-84 is orbited by five known planets, four small gas giants and a Super-Earth.[5]

gollark: That wouldn't destroy it.
gollark: The most feasible way would probably be to deorbit the earth with MANY mass drivers.

gollark: Destroying the earth is quite hard.
gollark: Technically heavier stuff can fuse but it's energy negative.
