Dwarf Planets facts

While investigating facts about Dwarf Planets In Our Solar System and Dwarf Planets Song, I found out little known, but curios details like:

There exists a planet between Mars and Jupiter known as Ceres. It's a dwarf planet, like Pluto, and may contain water and an atmosphere.

how dwarf planets in solar system?

The woman who (at age 11) suggested they name the newly-discovered trans-Neptunian celestial body "Pluto" lived long enough to see the International Astronomical Union demote Pluto to the status of "dwarf planet", 76 years later.

What dwarf planets are in the asteroid belt?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what dwarf planets are there. Here are 50 of the best facts about Dwarf Planets In The Solar System and Dwarf Planets In Order I managed to collect.

what dwarf planets are in our solar system?

There is a dwarf planet in our solar system that is 8 billion miles away and takes 10,000 years to complete one orbit around the Sun.
Triton, the largest moon of Neptune, is the only moon in our solar system with a retrograde orbit - an orbit in the opposite direction its planet, and is thus thought to be a dwarf planet that Neptune caught from the Kuiper belt.
Neil deGrasse Tyson assisted DC Comics in selecting a real-life star that would be an appropriate parent star to Superman's home planet Krypton. A red dwarf star in the constellation Corvus was chosen. Corvus is also Latin for "Crow" which is the mascot of Superman's high school.
Clyde Tombaugh, the astronomer who discovered Pluto, had some of his ashes placed aboard the New Horizons space probe, the spacecraft that first explored the dwarf planet
The Earth is the densest planet in our solar system. It is also denser than every dwarf planet, every moon, every major asteroid, and the Sun.
In 2005 another Kuiper Belt Object was discovered. This dwarf planet is called Eris and it is smaller than Pluto. It takes Eris 580 years to revolve around the sun.
There is a dwarf planet called Orcus that is referred to as the "anti-Pluto" because its orbit is almost a mirror image of Pluto's and, like Pluto, it has a proportionally large moon.
When Pluto was discovered in 1930 it was classified as a planet, making it the ninth planet in the solar system. However when the formal definition of a planet was established, Pluto was reclassified as a dwarf planet.
A dwarf planet like Pluto orbits the Sun and has enough mass to become a sphere (shaped like a smooth ball).
After 1992, Pluto's planethood was questioned following the discovery of several objects of similar size in the Kuiper belt. In 2005, when Eris was discovered at 27% more massive than Pluto, it led the International Astronomical Union to define the term planet formally for the first time the following year. This definition excluded Pluto and it was reclassified as a dwarf planet.

Why dwarf planets are called dwarf planets?

You can easily fact check why are dwarf planets not considered planets by examining the linked well-known sources.

Persephone was also considered as a name for Eris. Persephone was the wife of Pluto (also a dwarf planet). The dwarf planet also had the nickname Xena for a short time.

It was named by Berzelius after the Ceres dwarf planet that had been discovered only two years before.

Ceres is a dwarf planet that is believed to have surface features and a rocky core, making it very similar to the inner planets.

The International Astronomical Union officially recognizes five dwarf planets in our Solar System. They are Ceres, Haumea, Makemake, Eris and Pluto. Ceres is found in the outer Solar System and the other four are found in the asteroid belt. The largest is Pluto and the smallest is Ceres.

The most well-known dwarf planet Pluto has been somewhat controversial. Pluto was classified as the ninth planet of the Sun for 76 years. It was discovered on February 18, 1930 by Clyde W. Tombaugh.

When were dwarf planets discovered?

The dwarf planet Ceres makes up one third of the total mass of the asteroid belt

How dwarf planets are formed?

Haumea is the fourth largest of five dwarf planets known to exist.

Makemake is a known as a classical Kuiper belt object, which means its orbit lies far enough from Neptune to remain stable over the age of the Solar System. Like all the known dwarf planets, except Ceres, Makemake travels through the Kuiper Belt which is the region of ice and rock at the outer edges of the Solar System. It can travel as far out as 53 times the distance between Earth and Sun, and then come as close as 38 times over the course of its orbit.

Ceres was named after the Roman God of agriculture, who is also known as Demeter in Greek mythology. Originally Piazzi named the dwarf planet Cerere Ferdinandea, however it was changed after there were objections to Ferdinandea from other countries.

He and his team have discovered many trans-Neptunian objects, including a dwarf planet named Eris.

Ceres, a dwarf planet in the asteroid belt between Mars and Jupiter, was long considered a planet, and contains 1/3 the mass of the asteroid belt

What happens to the planets when the sun becomes a white dwarf?

Ceres was the first dwarf planet to receive a visit from a spacecraft. In 2015, NASA's unmanned spacecraft Dawn was the first ever to explore a dwarf planet. Dawn approached and orbited Ceres, sending scientific data and detailed images back to Earth. During this mission, Dawn also completed a survey mission to the protoplanet Vesta.

Ceres is the earliest known and the smallest of the dwarf planets. It was discovered in 1801 by Sicilian astronomer Giuseppe Piazzi. It is only 590 miles in diameter and has a mass of just 0.015 percent of the Earth. It is classified as both a dwarf planet and an asteroid. Ceres is the largest resident of the main asteroid belt between Jupiter and Mars. It is also the first dwarf planet to be visited by a spacecraft.

A Pluto-sized world, astronomers discovered Eris in 2003. It takes icy Eris 557 Earth years to complete a single orbit around the sun. All the asteroids in the asteroid belt would fit inside Eris. However, like Pluto, Eris is still smaller than the Earth's moon.

Eris was almost classified as the tenth planet. Following reclassification of planets, Eris and Pluto were both classified as dwarf planets. This reduced the number of planets in our solar system to only eight, rather than nine when Pluto had been a planet.

Nobody knows for sure how many dwarf planets exist in our solar system. Some of the known dwarf planets are Ceres, Pluto, Haumea, Eris and Makemake.

How many dwarf planets are there?

Pluto is not the only dwarf planet in the Kuiper Belt. Two other dwarf planets, Haumea and Makemake was discovered in 2004 and 2005 respectively.

His book, How I killed Pluto and Why it Had It Coming, explained why Pluto did not fit the International Astronomical Union's definition of a planet and why it now designated a dwarf planet.

Italian astronomer Giuseppe Piazzi discovered Ceres on January 1, 1801 at Palermo. He classified it as a planet, but then it was demoted to an asteroid in the 1850s when other objects in similar orbits were discovered. In 2006, it was promoted as a dwarf planet, a classification it shares with Pluto that is 14 times more massive.

Dwarf planets are smaller than the Solar System's smallest planet, Mercury. So far scientists have recorded 3 dwarf planets in our Solar System. They are Pluto, Eris and Ceres.

Brown and his team discovered a dwarf planet named Haumea but their website was hacked and a team from Spain reported the planet first.

In 2004 another Kuiper Belt Object was discovered. It is another dwarf planet called Sedna and is only 75% the size of Pluto.

The Kuiper Belt includes Pluto, Haumea, and Makemake, which are considered to be dwarf planets.

One of Gauss's most important contributions to astronomy stemmed from using conic equations to track the dwarf planet Ceres, whose own discoverer Giuseppe Piazzi could not locate it months after its discovery due to the limitations of available tools.

Pluto is not the only dwarf planet in our solar system. Ceres, Haumea, Makemake and Eris are officially recognized as dwarf planets, bringing the current total to 5.

There have only been two visits by space probes to dwarf planets. In 2015 NASA's Dawn and New Horizons missions reached Ceres and Pluto.

Pluto was demoted to dwarf planet status not because it was too small, but because it's not unique among a mass of objects that orbit the sun beyond Neptune.

Our solar system has five recognized dwarf planets: Ceres, Pluto, Eris, Makemake and Haumea. Scientists believe there may be dozens or even more than 100 dwarf planets awaiting discovery.
