How Long Does A Star Live?
Generally the more massive the star the faster it burns up its fuel supply and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun on the other hand can continue fusing hydrogen for about 10 billion years.Jul 15 2014
What is the average life span of a star?
Stars live different lengths of time depending on how big they are. A star like our sun lives for about 10 billion years while a star which weighs 20 times as much lives only 10 million years about a thousandth as long.
How fast does a star die?
Most stars take millions of years to die. When a star like the Sun has burned all of its hydrogen fuel it expands to become a red giant.
Can a star live forever?
Answer: No. Stars are born live and die. This process is called the “life cycle of a star”.
What is the shortest lived star?
Eta Carinae was probably formed less than 3 million years ago. It consumes fuel so fast in its core that it gives off 4 million times the energy of the Sun. Astronomers think that Eta Carinae has less than 100 000 years to live.
Do Dead stars still shine?
After a star dies there is still some residual heat left over. That heat makes the star (white dwarf or neutron star) glow even though it is not producing any energy. Eventually the star cools off and does indeed simply become a hunk of ash which we call a “black dwarf.”

Why do stars twinkle?
What is a shooting star?
noun. rocky debris from space that enters Earth’s atmosphere. Also called a meteor.
Why massive stars have shorter lifespans?
How are stars born?
Stars are born within the clouds of dust and scattered throughout most galaxies. … Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. As the cloud collapses the material at the center begins to heat up.
What star has the longest lifetime?
- Red Dwarf Stars. Astronomers define a red dwarf as a star having between about 0.08 and 0.5 times the mass of the sun and formed primarily of hydrogen gas. …

What is the closest star to Earth?
The closest star to Earth is a triple-star system called Alpha Centauri. The two main stars are Alpha Centauri A and Alpha Centauri B which form a binary pair. They are about 4.35 light-years from Earth according to NASA.

What Year Will the Earth die?
What if the sun exploded?
Is Jupiter a failed star?
“Jupiter is called a failed star because it is made of the same elements (hydrogen and helium) as is the Sun but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium the energy source that powers the sun and most other stars.
Can a star become a black hole?
Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars which are not massive enough to trap light.)
Can a star explode?
Learn more about what happens when stars explode. Some stars burn out instead of fading. These stars end their evolutions in massive cosmic explosions known as supernovae. When supernovae explode they jettison matter into space at some 9 000 to 25 000 miles (15 000 to 40 000 kilometers) per second.
What is the hottest color of star?
How old are the stars we see today?
For the most part the stars you see with the naked eye (that is without a telescope) are still alive. These stars are usually no more than about 10 000 light years away so the light we see left them about 10 000 years ago.
Why do stars have colors?
The color of a star is linked to its surface temperature. The hotter the star the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white which are shorter wavelengths of light. Cooler ones are red or red-brown which are longer wavelengths.
