13 Lyrae
Variable starWhat is 13 Lyrae
13 Lyrae is an M-type red giant whose brightness drifts slowly, a barely perceptible pulsation that betrays its unstable nature. It inhabits the small constellation of the Lyre, near the blue glare of Vega. Its light, released nearly three centuries ago, travels from an era when the spectroscopic telescopes that now read its composition did not yet exist.
