Gliese 3512 is a nearby star in the northern circumpolar constellation of Ursa Major. It is invisible to the naked eye but can be observed using a telescope, having an apparent visual magnitude of +15.05. The star is located at a distance of 31 light-years from the Sun based on parallax. It has a high proper motion, traversing the celestial sphere at the rate of 1.311″ yr−1. The measurement of the star's radial velocity is poorly constrained, but it appears to be drifting further away at a rate of ~8 km/s.

  • GJ 3512 (G 234-45) ist ein Stern der Klasse der roten Zwerge. Er liegt 31 Lichtjahre von der Sonne im Sternbild Großer Bär und wird von einem Gasplaneten (GJ 3512b) umrundet. Dieser Exoplanet wurde im Jahre 2019 entdeckt und ist im Verhältnis zum Stern ungewöhnlich groß. (de)
  • GJ 3512 est une naine rouge située à ∼31 a.l. (∼9,5 pc) de la planète Terre dans la constellation de la Grande Ourse. Sa magnitude apparente visuelle est de 15,05. Elle possède une planète confirmée, GJ 3512 b, d'une masse minimale qui est environ la moitié de celle de Jupiter. (fr)
  • GJ 3512とは、地球から見ておおぐま座の方向に存在する恒星である。見かけの等級は+15.05で、肉眼で観測することは不可能であるが、望遠鏡を用いることで観測が可能となる。GJ 3512は視差に基づいて太陽から31光年の距離に存在する。それは高い固有運動を持っており、1.311″ 年−1の速度で天球上を横断している。GJ 3512の視線速度の測定はあまり正確ではないが、約8km/sの速度で遠ざかっているとされる。 GJ 3512のスペクトル分類はdM5.5であり、これは核が水素核融合によってエネルギーを生成している小さな赤色矮星であることを示している。太陽のような14年の周期で適度な量の磁気活動を示している。~87日続く低レベルの変動は、おおよその自転周期と一致している。GJ 3512は太陽質量の12.5%、太陽半径の16%を持っている。有効温度は3,081ケルビンで、太陽光度の1.6%を放射している。 (ja)

  • Gliese 3512 is a nearby star in the northern circumpolar constellation of Ursa Major. It is invisible to the naked eye but can be observed using a telescope, having an apparent visual magnitude of +15.05. The star is located at a distance of 31 light-years from the Sun based on parallax. It has a high proper motion, traversing the celestial sphere at the rate of 1.311″ yr−1. The measurement of the star's radial velocity is poorly constrained, but it appears to be drifting further away at a rate of ~8 km/s. The stellar classification of Gliese 3512 is dM5.5, which determines this to be a small red dwarf star that is generating energy through core hydrogen fusion. It displays a moderate amount of magnetic activity with a Sun-like cycle lasting 14 years. A low-level variability lasting ~87 d matches the approximate rotation period. The star has 12.5% of the mass of the Sun and 16% of the Sun's radius. It is radiating 1.6% of the luminosity of the Sun from its photosphere at an effective temperature of 3,081 K. (en)
