HD 63454, formally named Ceibo, is a star located in the southern circumpolar constellation Chamaeleon near the border with Mensa. To see the star, one needs a small telescope because it has an apparent magnitude of 9.36, which is below the limit for naked eye visibility. The object is located relatively close at a distance of 123 light years based on Gaia DR3 parallax measurements but is receding with a heliocentric radial velocity of 33.8 km/s. At its current distance, HD 63454's brightness is diminished by two tenths of a magnitude due to interstellar dust. It has an absolute magnitude of +6.68.

<span class="mw-page-title-main">Theta Sculptoris</span> Star in the constellation Sculptor

θ Sculptoris, Latinized as Theta Sculptoris, is a star in the southern constellation of Sculptor. This object is visible to the naked eye as a dim, yellow-white hued star with an apparent visual magnitude of +5.24. It is located 71 light years from the Sun based on parallax. The object is drifting closer with a radial velocity of −21 km/s, and may come to within 49 light-years in half a million years.

53 Eridani, also designated l Eridani, is a binary star in the constellation of Eridanus. The system has a combined apparent magnitude of 3.87. Parallax estimates made by the Hipparcos spacecraft put it at a distance of about 110 light-years, or 33.7 parsecs, from the Sun.

Aldebaran b is a candidate exoplanet orbiting the orange giant star Aldebaran, 65 light-years away. It was initially detected in 1993, but was considered doubtful until 2015, when researchers came to a conclusion that there is likely an exoplanet orbiting Aldebaran, consistent with the original calculations, but also compatible with stellar activity. However, in 2019, new data placed doubts on its existence again.

HD 213429 is a spectroscopic binary system in the equatorial constellation of Aquarius. It has a combined apparent magnitude of 6.16 and is located around 83 light years away. The pair orbit each other with a period of 631 days, at an average separation of 1.74 AU and an eccentricity of 0.38.
