A white dwarf
It can be called a star cluster, an open cluster or an asterism.
Massive stars are most likely to explode faster than smaller stars.
No. But the sun is one of the smaller types of star called 'yellow dwarf''. There are smaller and bigger stars also.
That's an opinion, but if you meant temperature-wise, the answer would be smaller stars because of the gas and pressure.
Common groupings of stars within a constellation, or which overlap two or more constellations, are called "asterisms". For example, "Orion's Belt" is a smaller grouping within Orion, and the Big Dipper is a smaller grouping within Ursa Major, the Great Bear.
The five smaller stars represent the constellation of the Southern Cross.
Stars are smaller than the moon because they are further away. They're not actually smaller, its just because they are so far away. Stars are actually very large.
yes :) but some stars are actually smaller:)
Despite being larger than most stars, the sun is called a yellow dwarf because it is far smaller than the giant and supergiant stars.
If you mean "stars", the smallest real stars are called red dwarves. Brown dwarves may be smaller still, but since they don't fuse hydrogen-1 into helium-4, it's doubtful whether you should classify them as real stars.
Hotter.
Most stars are smaller than the sun, falling into the red dwarf category.
