Does Pluto is a planet?

How are planets named?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. Jupiter, Saturn, Mars, Venus and Mercury were given their names thousands of years ago. The other planets were not discovered until much later, after telescopes were invented. Mercury was named after the Roman god of travel.
Is there a 10th planet?
Astronomers have found a tenth planet, larger than Pluto and nearly three times farther from the Sun as Pluto is today. It also is the largest body yet found orbiting in the Kuiper belt, the group of icy bodies including Pluto which orbit beyond Neptune.
Why is Pluto not a planet?
According to the IAU, Pluto is technically a “dwarf planet,” because it has not “cleared its neighboring region of other objects.” This means that Pluto still has lots of asteroids and other space rocks along its flight path, rather than having absorbed them over time, like the larger planets have done.
Is the Sun White?
When we direct solar rays through a prism, we see all the colors of the rainbow come out the other end. That’s to say we see all the colors that are visible to the human eye. “Therefore the sun is white,” because white is made up of all the colors, Baird said.
Can you see the Sun from space?
Our sun is one object in the sky that everyone can see, but no one can look at. Far and away the brightest object in the sky, the sun is easy to find, but it’s so bright that one can’t look directly at it without vision damage. SOHO stands for Solar and Heliospheric Observatory.
Why is there a hole in the Sun?
NOAA explains that coronal holes are the dark spots that are visible on the surface of the Sun. They are areas where the Sun’s corona (read: the outermost part of the Sun’s atmosphere) is colder and less dense.
