Spectral type: M9 (Red dwarf, coolest) Surface temperature in the range: 2,400–3,700 K IR – Infrared wave source Mag: 15.35 Stars M class are most common. About 76% of the main sequence stars in the spectral band of the Sun (class G) are class M stars (red dwarfs), their brightness
Emission nebula in the constellation Orion. It’s around 1,500 ly away from Earth. The shape looks like a fired flame or a torch with an angular diameter of about 0.5 °, visible in the sky near the star Alnitak. The Flame Nebula has a reddish hue in visible light, which
The diameter is 4 light years. It surrounds the young massive star HD 37903 of spectral type B2 Ve. The energy of this star illuminates the nebula of molecular hydrogen, which emits near-infrared wavelengths and relatively high surface brightness. New stars are forming in the material from which the NGC
