YZ Canis Minoris
Star in the constellation Canis Minor
YZ Canis Minoris is a red-hued star in the equatorial constellation of Canis Minor. With an apparent visual magnitude of 11.15,[3] it is much too faint to be viewed with the naked eye. The distance to YZ CMi can be estimated from its annual parallax shift of 167 mas, yielding a value of 19.5 light years. Presently the star is moving further away with a heliocentric radial velocity of +26.5 km/s.[5] It made its closest approach some 162,000 years ago when it made perihelion passage at a distance of 10.2 ly.[13] YZ CMi is a potential member of the Beta Pictoris moving group.[14]
This is a red dwarf star, or M-type main-sequence star, with a stellar classification of M5 V.[4] It is a flare star, so called due to its stellar flares being more powerful than those of Earth's star, and is roughly three times the size of Jupiter.[15] The radio emission from the star is in a 50 mHz bandwidth and is centered on 1464.9 mHz.[16] The X-ray surface flux is 2.73×106 erg s−1 cm−2. It has a coronal temperature of 5.79 MK.[17]
