Pluto: dwarfPLANET

Growing up with Pluto being known as the ninth planet, I’m interested in Pluto, its uniqueness and why it was revoked of the prestigious planetary title. The discovery of other planetary objects in the outer solar system today known as dwarf planets made the switch of Pluto’s classification from a planet to a dwarf planet. […] Continue reading

The Heart of Pluto

Pluto’s beloved carotid glacier, Tombaugh Regio, has been the apple of astronomers’ eyes ever since New Horizons made its fly-by in 2015. This fly-by gave us the highest resolution images of Pluto we’ve ever been able to capture, and in these new photos, a particular feature on the dwarf planet’s surface rose to a meteoricContinue reading “The Heart of Pluto” Continue reading

A Dwarf Planet is Still Cool!

On August 24, 2006, the International Astronomical Union changed Pluto’s status from planet to dwarf planet.  This caused an outrage amongst the public.  Memes were created and shared expressing Pluto’s sadness at its “demotion” from planetary status.  Textbooks had to be changed and the general public was oddly passionate over an object in space’s official title.  Nevertheless, people wereContinue reading “A Dwarf Planet is Still Cool!” Continue reading

What Is A Dwarf Planet, Anyway?

Given all our discussions of Pluto and the other “dwarf planets” of our solar system, you may be interested in just how astronomers differentiate a dwarf planet from a “regular” planet. According to the ever-reliable Wikipedia (not being sarcastic, Wikipedia is generally very trustworthy these days!), there are three characteristics that define a dwarf planet. … Continue reading What Is A Dwarf Planet, Anyway?

Ceres

Ceres is a dwarf planet discovered by Giuseppe Piazzi in 1801. Its mass is only .015 percent of Earth’s and it is actually small enough to be classified as both a dwarf planet and an asteroid. Moreover it is sometimes referred to as the largest asteroid in the solar system. Ceres is round, though itContinue reading “Ceres” Continue reading

Kuiper Belt Objects (woah)

Was I the only one who thought that only the 8 main planets that everyone knows about + Pluto and a couple other dwarf planets, asteroids, and comets here or there were the only things that orbited our sun? Yeah well, I am very wrong, and if you thought that too, so are you :0.Continue reading “Kuiper Belt Objects (woah)” Continue reading

Why isn’t Pluto a planet?

Contrary to what Jerry Smith says in Rick and Morty, Pluto is not a planet. But why did Pluto lose this designation in 2006? The International Astronomical Union has 3 main criteria to determine what is a planet and what is not. These three criteria are: having an orbit around the sun, having sufficient massContinue reading “Why isn’t Pluto a planet?” Continue reading

Dwarf Perspective

There are many celestial bodies in the Kuiper Belt. One notable object is a dwarf planet named Makemake. This dwarf planet was one of the objects NASA used to demote Pluto from its previous planet status down to dwarf planet status. NASA wasn’t aware of other bodies that looked like Pluto, and when they foundContinue reading “Dwarf Perspective” Continue reading

Meet Makemake: The Dwarf Planet Partially Responsible for Pluto’s Demotion

Pluto was discovered in 1930, and was classified as a planet. In 2006, as most of us probably know, Pluto was reclassified as a dwarf planet. A significant amount of the population, whether justified or not, are opposed to the removal of Pluto from the official list of planets, primarily out of nostalgia for oneContinue reading “Meet Makemake: The Dwarf Planet Partially Responsible for Pluto’s Demotion” Continue reading

Makemake

Makemake is a reddish-brown dwarf planet in the outer solar system and the fourth body identified as a dwarf planet; it, along with Eris and Haumea, were responsible for Pluto’s drop in status from planet to dwarf planet. It is the second brightest known object in the outer solar system (behind Pluto) and is 870 miles (1,400 … Continue reading Makemake Continue reading
