Q: What is the approximate diameter of a white dwarf star with the Sun's mass?
A: White dwarf stars are about the same size as the Earth with the odd property that the more massive ones should be smaller than the less massive ones. A white dwarf with 1 solar mass would be slighty smaller than the earth, but not significantly so.
why does phuto turn into white dwarf.
The sun is about 4.57 billion years old and should survive another 5 billion years or so in its current state. After that it will run low on its hydrogen fuel, the fusion of which presently pushes away gas that would otherwise gather at its core. As the gas accumulates, rising pressure will fuse heavier helium atoms into carbon, drastically increasing the star’s core temperature.
That final blaze that will push away its outer gas shells, turning it into a red giant star. Its surface will extend roughly to the orbit of Earth.
“When this happens in our own solar system, billions of years from now, the Sun will engulf the inner planets Mercury and Venus,” Gänsicke said in the release. “It’s unclear whether the Earth will also be swallowed up by the Sun in its red giant phase — but even if it survives, its surface will be roasted.”
A)The white dwarf will collapse to become a black hole.
B)The white dwarf will collapse in size, becoming a neutron star.
C)The white dwarf will explode completely as a white dwarf supernova.
D)The white dwarf will undergo a nova
The white dwarfs in this group of stars have a range of colors and luminosities. What might be the difference between the brightest, hottest white dwarf and the faintest, coolest white dwarf?

Anthony Westbury: Rummaging for gold can really pay off It was a pencil-and-crayon rendering of the seven dwarfs of Snow White fame. Jean, who has had dealer space at Pineapple Pattie's antiques and consignment store in Fort Pierce since 2005, grabbed the picture for the princely sum of $3. |

Pulsar heavyweight champ challenges Einstein The fastest pulsars are in binary systems with another object, like a star or a white dwarf. The pulsar quickens its spin by stealing material from its companion. This arrangement can continue for billions of years before the two objects collide and |
