82 G. Eridani
star in the constellation Eridanus
82 G. Eridani (HD 20794, Gliese 139, e Eridani) is a star 19.7 light-years (6.0 parsecs) away from Earth in the constellation Eridanus. It is a main-sequence star with a stellar classification of G6 V, and it hosts a system of three confirmed planets and a dust disk.
Observation
In the southern-sky catalog Uranometria Argentina, 82 G. Eridani (often abbreviated to 82 Eridani) is the 82nd star listed in the constellation Eridanus. The Argentina catalog, compiled by the 19th-century astronomer Benjamin Gould, is a southern celestial hemisphere analog of the more famous Flamsteed catalog, and uses a similar numbering scheme.
Properties
82 G. Eridani is slightly smaller and less massive than the Sun, at around 80% of the Sun's mass and 90% of the radius. It has a luminosity 30% fainter than the Sun's. Spectroscopically, it is classified as G6V, compared to G2V for the Sun, and is among the nearest solar-type stars. The projected rotational velocity rate (v sin i) is smaller than 2 km/s, compatible with a slow-rotating or pole-on star relative to Earth. Such observation would also match the lack of a reliable rotational period detection and the absence of any magnetic cycle.
It is a high-velocity star—it is moving quickly compared to the average—and hence is probably a member of Population II, generally older stars whose motions take them well outside the plane of the Milky Way.
This brief starts where responsible research should: with the source description of “82 G. Eridani” as star in the constellation Eridanus. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as star in the constellation Eridanus. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q1195694. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
