Answer 2

No the sun's not a white-dwarf - it's a yellow-dwarf. The white-dwarf stage is at the end of a star's life, so they don't become red-giants. The sun's got about 5 billion years to go before it becomes a red-giant.

Answer 3

The sun is NOT in a white dwarf stage at this time -- that is what it will be after it completely runs out of fuel. Red giant phase will happen in about five billion years, when the core runs out of helium. I have estimated the date of this event as April 1, 5,000,000,147 AD, on the basis of no evidence whatsoever. (Note the day of the year.)

Answer 4

No it isn't, it's halfway thru its main sequence stage and has another five billion years to go before it runs out of hydrogen to burn. At that point it will expand to a red giant (vaporizing the inner planets including Earth) and eventually settle down to a white dwarf for a good long time.

Answer 5

Presently the Sun is NOT ANY KIND of dwarf star.
Its a medium yellow star.
It will take about 4.8 billion star to become a red-giant.
At this stage it will engulf all planets till mars.
After that when the outer shell collapses at about 5-5.1 billion years will it become a WHITE DWARF (scarcity of hydrogen results).
from then on it will continue to exist to about 15 billion years.

Answer 6

The sun is not a white-dwarf.
It will eventually swell up and lose surface temperature but it will never become a red giant,only a small one!

Answer 7

The sun is not in a white dwarf stage currently......

Answer 8

Som is closer....the Sun is a Medium Yellow star of G class in Main Sequence
