Are moon and sun the same?
No. The sun is the bright yellow thing in the sky. The moon is the big white thing in the sky.

Can you describe the moons atmosphere?
The moon has none so it's very clear, but on the bright side of the moon the sun is very bright and you have a hard time seeing stars.
What type of star is less bright than the sun?
On the main sequence, red dwarfs and orange dwarfs are less bright than the sun. Our sun is a yellow dwarf.
How is it possible for white dwarfs of have a lower luminosity than the sun even though the sun is much cooler than the white dwarfs?
Because luminosity is a measure of brightness over distance. Also white dwarfs are a hundred times smaller than the Sun. Most white dwarfs are a long way away and thus are difficult to see.
What kinds of stars are smaller than the sun?
There are other "main sequence" stars smaller than the Sun, but the classes of much smaller stars are:white dwarf stars (once Sun-like but no longer support fusion)red dwarfs and orange dwarfs (small dim stars that have very long lives)"brown dwarfs" (oversized Jovian gas giants with little or no fusion)neutron stars (smaller than the Earth but immensely dense, remnants of massive stars that went supernova)
How would the sun look from Pluto?
The sun would look much smaller than it does from Earth but still bright.
Are white dwarfs older than the sun?
Some white dwarfs are older than the sun, and some are not. More massive red dwarfs form from stars larger than the sun, which do not last as long.
Is a yellow star bigger than a red star?
There are two types of star that can be red. Red dwarfs are smaller than the sun. Red giants are far larger than the sun.
Is the sun bigger or smaller than other stars?
Our sun is about average compared to other stars. Some are much smaller (white dwarfs) and others are much larger.
What kind of stars become white dwarfs?
small ones, like our sun and smaller.
Is the sun a medium sized star or a yellow dwarf star?
The sun is a yellow dwarf star and as such is considered a medium-sized star. The term is something of a misnomer as the majority of stars are red dwarfs smaller than the sun. The term dwarf is used to distinguish how much smaller event the sun is than giant stars.
How does the sun look from Jupiter compared to how it looks from Earth?
From the vicinity of Jupiter, it would appear much smaller than from Earth, and about 1/27th as bright, like an extremely bright star.
Is the moon smaller than the sun and Earth?
yes the sun is the biggest out of all planets however the sun is a star.
Is the sun smaller than Betelgeuse?
Yes, the Sun is much smaller than Betelgeuse.
