HIP 84720
Cool red starWhat is HIP 84720
This red light left the Altar barely 29 years ago, when the Berlin Wall was falling and the world was learning the word «internet» beyond the laboratories. It is a dwarf M-type star, cool and reddish, similar to most of those that populate the galaxy. It lies so close that it could almost be counted among the Sun's neighbours, though its muted glow conceals it even under clean skies.
