The moon is less brighter than the sun.

The sun is the most brightest object in our solar system.

It even reflects off Pluto, which is farther away than any planet.

Pluto is also smaller than any planet.

Jupiter is the most largest planet.

Earth is the most largest of all the rocky inner planets.

The inner planets are less gassier than the outer planets, which are mostly gas.

Since all the planets were formed at about the same time, it is hard to say which ones are more older than the others.

Venus has a thick atmosphere that is more poisonous than Earth.

On the other hand, Mars has a more thinner atmosphere than Earth’s atmosphere.

The most loveliest sights in the solar system are the ring systems around some of the planets.

Of all the planets, Saturn has the most extensivest system of rings.

Because they are so large, Saturn’s rings reflect more sunlight and are more shinier than the rings of Jupiter.

Our moon looks bright to us because it is much more closer to Earth than the stars.

Saturn has the most moons of any planet.

The sun is smaller and less hotter than many other stars.

The sun is, of course, the most closest to Earth of all stars.

Even though the star Proxima Centauri is 4.3 light years away from our sun, it is still closer than any star.

Astronomers have learned how to tell which stars are more farther away than other stars.

If several stars have the same magnitude, or true brightness, the star that is the most faintest is the farthest away.

The most brightest of all stars are supernovas.

These are huge stars that explode at the end of their lives, and shine brighter than anything else around them for many months.

After a supernova explodes, the remaining matter falls inward to become the most densest of all stars, a neutron star.

Even though a neutron star is small, its dense makeup makes it heavier than any other star.

Some supernovas collapse inward to form a black hole, where the gravity is stronger than that of other stars.

The sun can never be a supernova, because such a star must be much more massive than the mass of our sun.

The sun will expand and become a red giant eventually, and its surface temperature will become more lower than its temperature at present.

As the sun expands, in several billion years, the surface of Earth will become the most hottest it has ever been.

Star color is one way astronomers can tell which stars are the hottest and the most coolest.

Yellow stars, like our sun, are cooler than stars that are white or blue-white.
