Epsilon Indi
From Halopedia, the Halo wiki
Epsilon Indi (ε Ind / ε Indi), located in a system of the same name, is a star approximately 3.63 parsecs from the Sol System. This star has the second highest proper motion (second only to 61 Cygni) of any naked eye star, or possibly the third highest, since the magnitude 6.4 Groombridge 1830 is a naked eye star under exceptionally dark skies.
Epsilon Indi was home to a human colony, Harvest, until 2525 when it was attacked and glassed by the Covenant in search for Forerunner artifacts.
It is also the first human star system known of that the Covenant entered.
