Rigel

STAR LIFE CYCLE

Stellar NebulaA huge globe of gas and dust condenses under its own gravity.

Black DwarfCooled down leftovers

Planetary NebulaPeaceful death After expansion the gravity stops acting as strong and outer layers start to drift away.

Neutron StarThe hard core is left

Black Hole (really big star)The gravity becomes too much and everything collapses in itself. Not even light can escape.

SupernovaEnergetic and violet deathThe remains scatter around the Universe in an explosionAfter the rebound.

Red SupergiantStar of greater mass expands, cools and turns red.

White DwarfHot leftovers

Red GiantThe small star expands and cools down, swallowing nearby planets

Small StarStar shines as nuclear reactions inside produce Light and Heat.This star runs out of fuel slow.

Large StarStar shines as nuclear reactions inside produce Light and Heat.This star runs out of fuel fast.

Rigel Radius:Around 75 times the radius of the Sun.Size: 54.29 million kmHow old the star is:Rigel is only around 8 million years old and has already exhausted the supply of hydrogen in its core. The star is only 10 million years old, compared to the sun's 4.5 billionWhich part of the life cycle is the star in currently:Rigel is on the main sequence stage of its life.

Temperature: Rigel is estimated to have surface temperatures of around 12,000C (22,000F), more than twice as hot as the Sun.Colour:White Brightness/ magnitude:0.12, which is 47,000 times greater than the Sun.Size/ diameter/ radius:Diameter: Approx. 65 million miles (105 million km) - 75 x Sun.
