Detailed explanation-1: -Our Sun is a medium-sized star with a radius of about 435, 000 miles (700, 000 kilometers). Many stars are much larger – but the Sun is far more massive than our home planet: it would take more than 330, 000 Earths to match the mass of the Sun, and it would take 1.3 million Earths to fill the Sun’s volume.

Detailed explanation-2: -They develop an understanding that stars vary in their size and distance from Earth. The sun is a medium size star that appears larger and brighter than other stars because it is closer to us.

Detailed explanation-3: -They range from the size of a city, to large enough to swallow half our Solar System! Neutron stars pack a lot of mass into a small volume. They may contain the mass of one or two Suns but are often just 20 to 40 km in diameter. White dwarf stars are a bit bigger-often similar in size to our planet Earth.

Detailed explanation-4: -The Sun is a yellow dwarf star, which means it is a medium size star. It is believed to be over 4 billion years old. The Sun spins slowly on its axis as it revolves around the galaxy. The center, or core, of the Sun is very hot.

Detailed explanation-5: -For our Sun, we’re going to become a white dwarf after less than another 10 billion years, will fade to a black dwarf after  1014-1015 years, and will get ejected from the galaxy after 1017-1019 years.
