9 Ceti

9 Ceti is the Flamsteed designation for a star in the equatorial constellation of Cetus. It has an apparent visual magnitude of 6.39, which is below the limit that can be seen with the naked eye by a typical observer. (According to the Bortle scale, it is possible for some observers to see it from dark rural skies.) Based upon measurements made by the Hipparcos spacecraft, this star is around 68 light years away from the Sun. There is a magnitude 12.57 optical companion at an angular separation of 214 arc seconds along a position angle of 294° (as of 1999), although the pair are not physically associated as they have different proper motions.

This is a solar analog, which is defined as a "Population I dwarf with gross properties not very different from those of the Sun". It is a G-type main sequence star with a stellar classification of G3 V, which means it is generating energy through the fusion of hydrogen into helium at its core. The mass and radius of the star are similar to the Sun, although the abundance of elements other than hydrogen and helium is about 50% greater. It is much younger than the Sun, being an estimated 850 million years of age. The effective temperature of the stellar atmosphere is around 5,807 K, giving it the yellow-hued glow of a G-type star.

54 Ceti

54 Ceti is an older Flamsteed designation for a star that is now located within the constellation boundaries of Aries, the Ram. In the present day it is known by star catalogue identifiers like HD 11257 or HR 534. At an apparent visual magnitude of 5.94, it can be seen with the naked eye. The distance to this star, as determined using parallax measurements made during the Hipparcos mission, is approximately 139 light-years (43 parsecs), give or take a 6 light-year margin of error. It is located near the ecliptic and hence is subject to occasional occultations by the Moon and planets.

This is an F-type main sequence star with a stellar classification of F2 Vw, where the 'w' indicates weak absorption lines in the spectrum. It is a candidate member of the Ursa Major Moving Group, which has an estimated age of 500 ± 100 million years.
