No. There is a theoretical maximum mass that any star can have, and when a star is that massive, the light pressure of the radiation from the star is powerful enough to push any additional mass away from the star.
We're not sure exactly what that maximum mass is, yet; many astronomers believe that it is in the neighborhood of 150 solar masses (although more massive stars have been observed). But even a star that large is less than one light-hour in diameter. (In comparison, the orbit of the Earth around the Sun has a radius of a little over eight light-MINUTES.
if those are the only 4 options then the star that is 11.9 light years away is the closest
Barnard's star is about 6 light years away from the sun.
The light from a star eight light years away will take eight years to reach Earth.
The star Mintaka is approximately 916 light years away from Earth.
No. A neutron star is quite small, generally only a few miles across. A nebula is light years across.

Yes, a nebula is far larger than a neutron star. A neutron star is a few miles across. A nebula is light years across.
It depends on the size of the star. A G-type star,like the sun,is probably about 860,000 miles across. A light-year is 6,200,000,000,000 miles! But the universe itself is over 28 billion light-years across. So,a star is very,very small compared to the universe.
Quite simply, you don't. You see the star in the past - this may be 4 years in the past, in the case of Rigil Kentaurus, 30,000 years for a star in the center of our Milky Way, 2-3 million years in the case of the Andromeda Galaxy, or billions of years in the case of a quasar (the latter is not a star).
The distance to a star located 100 light years away from Earth is 100 light years.

No. A neutron star is quite small, generally only a few miles across. A nebula is light years across.
The most recent information we can receive about the star would be from about 100 years ago, as it takes light around 100 years to travel a distance of 100 light years from the star to reach us on Earth.
Probably you mean Alpha Centauri. That star is about 4.4 light years away.
