The planet Pluto is not given the respect of other planets and some have designation to be changed to ‘minor planet’. Astronomer Brian Marsden of Harvard Smithsonian Center said if Pluto were discovered seventy years ago, it would be considered a minor planet number. A minor planet is a term used to describe asteroids and most astronomers agree that Pluto is no asteroid.
Marsden said it’s not a demotion for Pluto to be referred to as the 10,000th minor planet, it is an honor.
Some astronomers do not agree with the Brian Marsden theory. Pluto deserves to be considered more than just a minor planet. Most astronomers would probably consider stripping Pluto of is status akin to stripping [the U.S. state of] Connecticut or Vermont of statehood because Texas and Alaska later joined. It was estimated that Pluto contained mass of eleven Earth but dropped rapidly over time. This is what is giving the astronomers a second opinion about being a planet.
Pluto is about 1,500 miles in diameter, larger than the largest asteroid. It is known to have density of two grams per cubic centimeter, so is estimated to be sixty percent rock and forty percent ices of frozen nitrogen, carbon monoxide, methane, and water.
