Class of stars Brown dwarf

Brown dwarfs are not really stars, because there is no thermonuclear fusion in their core. These objects are smaller and cooler than stars, but too massive to be considered planets.

Stellar Brief

3. 11. 2026

An Earth-sized planet circles its red dwarf host every 7.05 hours, while another candidate may orbit in a habitable zone. The latest findings also track a giant planet’s slowly shifting orbit, use the colors of HD 100546’s disk to probe its dust, and reveal how computer models interpret exoplanet atmospheres.

About Stellar Catalog

Working with real data

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

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

Stellar Catalog is continuously updated with new information from research papers. Stellar and planetary data are validated by automatic processes as well as humans.
