Pluto is the second most massive dwarf planet. Initially it was considered 9th planet of our solar system but a debate raged for 75 years over its legitimacy as a planet. Discovery of Eris a much bigger body urged International Astronomical Union to describe in 2006 what a planet is. According to the definition Pluto was stripped of its planetary status.
What else can I help you with?
What Pluto observations did not help convince scientists to change Pluto's status from that of a planet?
Observations of Pluto's orbit and size did not provide enough evidence to change its status from a planet. Astronomers cited factors such as its small size and irregular orbit as reasons for excluding it from the planetary classification.
Do all astronomers think that Pluto is a planet?
No, not all astronomers consider Pluto a planet. Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union, leading to debate among scientists about its classification. Some astronomers argue that Pluto does not meet all the criteria to be considered a full planet.
Is Pluto a planet in 2011?
In 2011, Pluto was classified as a "dwarf planet" by the International Astronomical Union. This decision downgraded Pluto from its previous status as the ninth planet in our solar system.
Can you explain the controversy about Pluto?
The first controversy over Pluto is that its orbit is not in the same plane (flat) as the rest of the planets. It also has different characteristics from the other planets. Some think that it is a comet that lost its moisture and was captured by our Sun's gravity.
How did Pluto's exit affect our solar system?
Pluto's reclassification from a planet to a dwarf planet did not have a significant impact on the dynamics or functioning of our solar system. The decision was made to scientifically categorize objects based on their characteristics rather than on sentimental or historical reasons. Pluto's change in status does not change its physical properties or its place in the solar system.

Is Pluto a planet in 2015?
The International Astronomical Union "demoted" Pluto from true planet to dwarf or minor planet status in 2006; it is highly unlikely to reverse that decision and change the definition back to include Pluto as a planet in 2015.
Do astronomers think Pluto is a planet?
Astronomers think Pluto is a dwarf planet. And they're right.
Is Pluto a planet in 2011?
In 2011, Pluto was classified as a "dwarf planet" by the International Astronomical Union. This decision downgraded Pluto from its previous status as the ninth planet in our solar system.
Who changed Pluto to a dwarf planet?
The International Astronomical Union, the world-wide association of astronomers. The decision remains controversial, even among astronomers, and it is possible (although perhaps unlikely) that it will be reconsidered.
Can you explain the controversy about Pluto?
The first controversy over Pluto is that its orbit is not in the same plane (flat) as the rest of the planets. It also has different characteristics from the other planets. Some think that it is a comet that lost its moisture and was captured by our Sun's gravity.
Do all astronomers think Pluto is a panet?
No. There are almost no astronomers that think Pluto is a planet. They know it's officially a dwarf planet.
Why don't astronomers think Pluto should not be called a planet?
Pluto has been the ninth planet in our solar system ever since it was discovered. However, as a small rocky planet with a very strange orbit, it doesn't really fit in with the rest of the gaseous outer planets. Pluto is much more similar to a group of objects called Trans-Neptunian Objects (TNOs), or asteroids. So, some astronomers don't think Pluto should be called a planet.The International Astronomical Union (IAU) gets to decide questions for astronomers around the world. They have been talking about Pluto's status, and what it should be called. Since Pluto is very important to a lot of people, the IAU isn't going to take away Pluto's status as a planet. They are talking about calling Pluto both a planet and a TNO, but Pluto still is and will be a planet!
How did Pluto's exit affect our solar system?
Pluto's reclassification from a planet to a dwarf planet did not have a significant impact on the dynamics or functioning of our solar system.
