What does G2 mean in a star?
… Sun is classified as a G2 V star, with G2 standing for the second hottest stars of the yellow G class—of surface temperature about 5,800 kelvins (K)—and the V representing a main sequence, or dwarf, star, the typical star for this temperature class.
What are stars Kid definition?
Stars are huge, glowing balls of gases. The closest star to Earth is the Sun. Most of the pinpricks of light that shine in the night sky are also stars. Countless more stars are too far from Earth to be seen without a telescope. Most stars are incredibly far away.
What are stars for Class 2?
A star is an exploding ball of burning gas held together by gravity. Our sun is a star! It produces great amounts of energy in the form of light and heat that provide the perfect conditions for life on Earth.
What is a large star called?
giant star, any star having a relatively large radius for its mass and temperature; because the radiating area is correspondingly large, the brightness of such stars is high.
How are stars classified for kids?
Stars are classified based on their spectra – the elements which they absorb, and their temperature. O-type stars are the hottest, and they are rare; however, M-type stars are the coldest, and they are quite common.
What is stars made up of for Class 3?
Stars are balls of hot, explosive gas that make their own light and heat energy. They’re mostly made up of two gases called hydrogen and helium.
