Star CD-35 2722

CD-35 2722 is a star system located approximately 73 light-years from the Sun. The primary star, CD-35 2722 A, is an object with an estimated mass of 0.4 solar masses. The system is notable for its substellar companion, CD-35 2722 B, a brown dwarf—an object too small to sustain the hydrogen fusion that powers typical stars—which serves as the host for the recently identified satellite candidates.

Star mass
Mass of the star CD-35 2722 A is 0.4 solar masses.

The mass of a star is the total amount of matter it contains. It is one of the most important properties of a star, as it determines almost everything about how the star lives, changes, and dies. In astronomy, star mass is usually measured in solar masses (M☉) — where 1 solar mass is equal to the mass of our Sun... icon More about Star mass in StellarGuide

Star size
Radius of the star CD-35 2722 A is not known. Its estimated value based on other similar stars is about 40 % solar radii.

The size of a star refers to its radius — the distance from its center to its surface. Star size is usually measured in solar radii (R☉), where 1 solar radius equals approximately 696,000 kilometers. Depending on their type and life stage, stars can be much smaller or larger than the Sun... icon More about Star size in StellarGuide

Star temperature
Surface temperature of CD-35 2722 A is estimated to be 3702 K, which is 64 % of the temperature on the surface of the Sun.

The temperature of a star refers to the temperature at its surface, also called the photosphere. It is measured in kelvins (K), the standard unit for temperature in astronomy. A star’s temperature tells us a lot about its physical properties and where it stands in its evolutionary stage... icon More about Star temperature in StellarGuide

A star’s hidden vibrations, a planet’s escaping helium, and worlds wrapped in shifting clouds reveal how much can be learned from changing light. Recent observations trace WASP 121’s surface motions in infrared for the first time, map the uneven clouds of WASP-43 b, and catch helium streaming ahead of TOI-3884 b. Light patterns also place the massive star HD 74371 on a return journey toward bluer colors after its red supergiant phase, while search interest spans Proxima Centauri b, Alpha Centauri, and many other stellar neighbors.
