Gravity and Heat.
Yes, an M-class planet can survive in a nebula, especially if it orbits a small star. The planet's ability to maintain its atmosphere and conditions for habitability would depend on factors such as the density and composition of the nebula, the intensity of radiation from the star, and the planet's distance from the star. If conditions are favorable, the nebula might even provide some protection from cosmic radiation, allowing the planet to thrive.
Yes, a nebula is far larger than a neutron star. A neutron star is a few miles across. A nebula is light years across.
The Sun is a star, specifically a G-type main-sequence star, which is the star at the center of our solar system. It is not a planet or a nebula.
cassiopeia
Star formation starts in a nebula.
Nebula
a nebula is cloud of particles which forms into a star.
A nebula may condense and ignite to become a star, conversely a star may explode and form a nebula.
A White Dwarf Star remains.
A Nebula is a gas of dust and minerals that surrounds a star. Also, a nebula is a birthplace of a star, where a star and sometimes a solar system is formed after a huge explosions

A star like our sun will shed a planetary nebula after its 'death'
No, a neutron star can't become a nebula. A neutron star is not made of atomic matter, has less mass than a nebula, and has no mechanism by which to expand.
No, Arcturus is a red giant star, not a nebula.
Yes, a nebula is far larger than a neutron star. A neutron star is a few miles across. A nebula is light years across.
protostar or nebula
There is no such thing as a nebula star.
