Star position
The position of a star tells us where it appears in the sky, similar to how we use coordinates like latitude and longitude on Earth. In astronomy, the three main coordinates are right ascension, declination and distance. .. icon More about Star position in StellarGuide

Star mass
Mass of the star TOI 5916 is 0.518 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 TOI 5916 is 0.487 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 TOI 5916 is 3541 K, which is 61 % 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
luminosity icon
Luminosity: 0.0349 L Sun

Star luminosity
Luminosity is the total amount of energy a star gives off every second. Think of it as the star’s true brightness — not just how bright it looks from Earth. This is important because some stars may appear dim simply because they are far away, not because they’re actually faint... icon More about Star luminosity in StellarGuide

Class of stars Red dwarf
Red dwarfs are small, cool stars with surface temperatures of about 2,000–3,800 K, much cooler than the Sun. They usually have 8–50% of the Sun’s mass and shine very faintly, sometimes at just a tiny fraction of the Sun’s brightness. Classified mainly as spectral type M, they are the most common stars in the Milky Way, making up roughly 70–75% of its stellar population.

They fuse hydrogen slowly through the proton–proton chain and are fully convective, which allows them to use their fuel very efficiently. As a result, red dwarfs can live for tens of billions to trillions of years—far longer than the Sun. Many exoplanets orbit red dwarfs, including some in close habitable zones, though strong stellar activity can affect planetary environments.

A planet’s escaping helium, a star’s hidden infrared rhythms, and a possible distant world in the WISPIT 2 system reveal how much we can learn by watching light across the spectrum. New observations also trace the changing radio and X-ray activity of young V1298 Tauri, while detailed models map cloudy and clear regions across the hot Jupiter WASP-43 b.

Working with real data
icon Data in Stellar Catalog come from trusted scientific sources. Primary source is Gaia space telescope mapping the stars in Milky Way. Other sources include research papers, Simbad catalog and Exoplanet.eu database.
Estimated values
icon Objects listed in the Stellar Catalog often have values that are estimates. These estimates are determined using their known characteristics, such as spectral type, brightness across different wavelengths, distance from a star, and other factors.
Fresh and validated
icon Stellar Catalog is continuously updated with new information from research papers. Stellar and planetary data are validated by automatic processes as well as humans.
Get your next news from nearby stars
Stellar Catalog brings the stars from our galaxy to you. Discover their position, physical properties and whether there are any exoplanets or disks orbiting them. The data in Stellar Catalog come from respectable sources like Gaia space telescope, or SIMBAD database.
