Oct 18, 2024 · F-type stars are yellow-white, reach 6,000–7,400 K, and display many spectral lines caused by metals. The Sun is a class G star; these are yellow, with surface temperatures of 5,000–6,000 K. Class K stars are yellow to orange, at about 3,500–5,000 K, and M stars are red, at about 3,000 K, with titanium oxide prominent in their spectra.
Stellar Classification | The Schools' Observatory
The hotter stars are usually much less common than the cooler, redder ones. For example 'O' type stars make up only 1 in every 3 million stars we see. The next hottest, 'B' stars are more common, making up 1 in 800. Then each cooler subtype gets more and more common. The coolest 'M' type stars make up 75% of all of the stars we see.
Types of Stars: What are the Different Types of Stars?
Each star type is unique, with its size, brightness, and life cycle. In astronomy, stars are sorted into seven main groups: O, B, A, F, G, K, and M. This system helps us learn about them. The hottest stars are O-type, while the coolest are M-type. The grouping system used is called the Morgan-Keenan (MK) system.
