A potential new dwarf planet has been discovered in the outer reaches of the solar system, and its existence poses the ...

Scientists may have discovered a dwarf planet far beyond Neptune — an unearthing that may disprove a longstanding theory ...

The dwarf planet also has one provisional moon, which is nicknamed MK 2. Discovery: March 31, 2005. Size: 888 miles in diameter (1/9 the size of Earth) Distance from sun: 4.3 billion miles.

For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

The dwarf planet's orbit is such an elongated ellipse that it takes around 25,000 years to make one orbit of our sun. At its closest, it sits approximately 6.66 billion kilometers away from the sun.

A dwarf planet called 50000 Quaoar that orbits beyond Neptune appears to have a ring that shouldn't be there, at 7.4 times more distant than the planet's radius.

6 planets align this January in a celestial late Friday/Saturday evening parade A six-planet alignment or parade will form an arc in the early night sky, peaking in visibility Jan. 17-18.

Five or six planets seen together make a large planetary alignment, and all of the Solar System’s planets (even occasionally including dwarf planet Pluto) seen together makes what’s called a ...

The ring in question orbits Quaoar, a small dwarf planet that lies more than 4 billion miles from the sun—roughly 44 times the distance between Earth and our star.

There are eight planets in our solar system and one dwarf planet (Pluto). Because we live on Earth, the most we could see is a maximum of seven planets total.
