pluto is a considered dwarf planet
Pluto was discoverd by actdent in the 1930’s
Pluto is smaller then seven of the solar system’s moons.

1. Pluto is no longer considered a major plantet, it is considered a dwarf planet
2. A planet must meet 3 requirements to be considered a major planet. Pluto only meets 2 of the 3 requirments.
3. The requirement that Pluto is missing to be considered a major planet is it doesn’t have enough mass and gravity to clear space around it.

Pluto is much smaller then earth : It is very cold : Pluto has at least three moons

3 facts about Pluto are:
Its 44 degrees higher from absolute zero.
It was first discovered back in 1985, when astronomers watched as Pluto passed in front of a star.
Finally, Pluto was named a “dwarf planet” on 2006.

Pluto is not considered a planet
Pluto does not have enough mass to clear space around it.
Pluto’s moon is called Charon.
Pluto is a dwarf planet.

Hi Seymour Simon here’s my three facts of Pluto.
1. Even though Pluto’s average temperature averages a mere 44 degrees above absolute zero, the dwarf planet has an atmosphere. Not an atmosphere as we know it, but an atmosphere, none the less.
It was first discovered back in 1985, when astronomers watched as Pluto passed in front of a star. They were able to calculate a slight dimming as its atmosphere passed in front of the star, before Pluto itself blocked the star entirely. From those observations, they were able to calculate that it has a thin envelope of nitrogen, methane and carbon dioxide.
As Pluto moves away from the Sun, this atmosphere gets so cold that it freezes onto the surface. And then as the dwarf planet warms again, the atmosphere evaporates again, forming a gas around it.
2. For most of its orbit, Pluto is more distant than Neptune, reaching out as far as 49 astronomical units (49 times the distance from the Earth to the Sun). But it has such an eccentric, elliptical orbit that it gets much closer, reaching a mere 29 AU. And during that time, it’s actually orbiting within the orbit of Neptune. The last time Pluto and Neptune made this switch was between February 7, 1979 and February 11, 1999. And give it another couple of hundred years and it’ll happen again.
Last one 3. Although Pluto orbits the Sun and it’s round, it’s not a planet. And that’s because Pluto hasn’t cleared out its orbit of material. This was the reason that the International Astronomical Union chose to demote it from planet to dwarf planet in 2006.
Just to give you an idea, if you added up the mass of all the other objects in Pluto’s orbit, Pluto’s mass would only be a tiny fraction of that total. In fact, it would only be 0.07 times as massive as everything else. For comparison, if you did the same thing with all the other material in the Earth’s orbit, our planet would be 1.5 million times as massive.
Wish I could stick around but that’s my three facts!

Well I know a lot more about Pluto, but as you instructed I gave three only

Three facts about pluto
pluto has not been visited by spacecraft
now classified as ‘‘dwarf planet’’
smaller than 7 solar systems

3 Cheers for Pluto
1. Pluto was the smallest planet until August 2006, when the International Astronomical Union reclassified it as a dwarf planet.
2. Pluto is the 2nd largest known dwarf planet and 10th largest orbiting the sun.
3. Pluto was discovered in 1930.

Pluto is not consider a planet any more! Well Pluto has 3 moons and is cold. Pluto dwarf planet.
