Niku is an object that orbits our Sun, but at a great enough distance to be considered a “trans-neptunian object”. Objects with an average orbital distance from the Sun greater than the orbit of Neptune (at 30 AU), earn this tag. Niku is likely to be a chunk of rock, but it might also contain […]

Pluto was once categorized as a planet, because we didn’t have a clear definition of what a planet is and because the objects we called planets were basically all the large objects we found orbiting the Sun. But then things changed. Around the year 2000, a team of astronomers headed by Mike Brown began discovering […]

Oort Cloud

In 1950, Dutch astronomer Jan Oort (building on an idea originated by Ernst Opik) proposed that a hypothetical and massive cloud of comets that orbit far from the center of our solar system might explain why comets don’t seem to originate from deep space and often have an outer orbital edge about 20-50,000 AUs from […]

Kuiper Belt

Discovered in 1992, the Kuiper Belt is a large expanse of space just outside the edge of our solar system that contains a large number of small objects. This belt is similar to the asteroid belt, but is much larger, much farther away and may contain more frozen water and volatile gases than the metallic […]
