New Small Planet as dense as Pure Iron discovered

A small planet that is as dense as pure iron has been discovered hurtling around a nearby star like a cannonball.The rocky planet, which lies about 30 light-years away in the constellation of Vela, is about three quarters of the size of Earth and half as massive.

Dubbed GJ 367 b, the little world takes less than eight hours to orbit a red dwarf star half the size of our Sun. Its high density suggests the planet is dominated by an iron-rich core, like Mercury.
