HD 47536 is likewise an ageing orange giant found to have a planetary system—echoing the fate of the Solar System in a few billion years as the Sun ages and becomes a giant. [78] Conversely, HD 45364 is a star 107 light-years distant that is a little smaller and cooler than the Sun, of spectral type G8V, which has two planets discovered in 2008.
Its name means "before the dog" or "preceding the dog" in Greek, as it rises an hour before the "Dog Star", Sirius, of Canis Major. It is a binary star system, consisting of a yellow-white main-sequence star [ 30 ] of spectral type F5 IV-V, named Procyon A, and a faint white dwarf companion of spectral type DA, named Procyon B. Procyon B, which ...
Initially, the names given to minor planets followed the same pattern as the other planets: names from Greek or Roman myths, with a preference for female names. With the discovery in 1898 of the first body found to cross the orbit of Mars, a different choice was deemed appropriate, and 433 Eros was chosen.
In Greek and Roman mythology and religion, Sirius (/ ˈ s ɪ r ɪ ə s /, SEE-ree-əss; Ancient Greek: Σείριος, romanized: Seírios, lit.

Canes Venatici (/ ˈ k eɪ n iː z v ɪ ˈ n æ t ɪ s aɪ / KAY-neez vin-AT-iss-eye) is one of the 88 constellations designated by the International Astronomical Union (IAU). It is a small northern constellation that was created by Johannes Hevelius in the 17th century.
The traditional name Chara was originally applied to the "southern dog", but it later became used specifically to refer to Beta Canum Venaticorum. Chara (χαρά) means 'joy' in Greek . [ 14 ] In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) [ 15 ] to catalog and standardize proper names for stars.
For instance, for a large portion of names ending in -s, the oblique stem and therefore the English adjective changes the -s to a -d, -t, or -r, as in Mars–Martian, Pallas–Palladian and Ceres–Cererian; [note 1] occasionally an -n has been lost historically from the nominative form, and reappears in the oblique and therefore in the English ...
