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 Lacaille 9352 is 0.495 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 Lacaille 9352 is 0.468 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 Lacaille 9352 is 3688 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

Star age
Star Lacaille 9352 is 2.9 billion years old, which is about 0.63 of the Sun's age.

The age of a star tells us how long it has been shining since it formed. Knowing a star’s age helps astronomers understand its life stage, how it has changed over time, and what will happen to it in the future... icon More about Star age in StellarGuide

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.
