Star Surface Temperature Calculator

Here’s a comprehensive table summarizing important information about the surface temperatures of various types of stars. The table includes the star type, its typical temperature range, color, and example stars.

Star Type	Surface Temperature (K)	Color	Example Stars
O-Type Stars	30,000 – 50,000	Blue	Zeta Puppis, Alpha Centauri
B-Type Stars	10,000 – 30,000	Blue-White	Rigel, Spica
A-Type Stars	7,500 – 10,000	White	Sirius, Vega
F-Type Stars	6,000 – 7,500	Yellow-White	Procyon, Canopus
G-Type Stars	5,300 – 6,000	Yellow	Sun, Alpha Centauri A
K-Type Stars	3,800 – 5,300	Orange	Arcturus, Aldebaran
M-Type Stars	2,400 – 3,800	Red	Betelgeuse, Proxima Centauri
L-Type Stars	1,300 – 2,400	Dark Red	2MASS J0036142+1821102
T-Type Stars	700 – 1,300	Brownish	SDSS J053951.99+004102.0
Y-Type Stars	< 700	Dark Brown	WISE 1828+2650

Key Points:

• O-Type Stars: The hottest, with high luminosity and short lifespans.
• B-Type Stars: Very luminous and hot, often found in young stellar populations.
• A-Type Stars: Bright, white stars that are often used as standards for stellar classification.
• F-Type Stars: Slightly cooler than A-types, often showing a yellow tint.
• G-Type Stars: Includes our Sun, these stars have stable temperatures and can support life.
• K-Type Stars: Cooler and more stable than G-type, often have long lifespans.
• M-Type Stars: The most common type of stars in the universe; they have low temperatures and long lifespans.
• L, T, and Y-Type Stars: Brown dwarfs with very low temperatures, often referred to as “failed stars.”
