NASA's Dawn spacecraft is currently on its way to the asteroid belt where it will rendezvous Ceres, its largest celestial body. Ceres, also classified as a dwarf planet, has an average diameter of about 950 km (590 miles) making it...

Between the orbits of Mars and Jupiter is a mysterious dwarf planet called Ceres. Its surface is dark and muddy, but has hundreds of patches of bright material.

NASA's Dawn mission finished in 2017. What did it discover while in orbit around Ceres?

Learn why Pluto was once considered a planet but is now classified as a dwarf planet. The video discusses the discovery of the Kuiper Belt and the debates that led to the reclassification of Pluto.

In this video, the topic of discussion is the Kuiper Belt, a region in our solar system that extends from the orbit of Neptune. It is similar to the asteroid belt but much larger, and is home to three recognized dwarf planets, including...

Astronomers using the Hubble Space Telescope discovered a moon orbiting dwarf planet Makemake -- the third largest known object past the orbit of Neptune, about two thirds the size of Pluto. Further observations of this moon may...

NASA’s New Horizons spacecraft is speeding towards Pluto for the first-ever flyby on July 14, 2015. Scientists are eager to collect data on the dwarf planet’s chemical and atmospheric makeup, and the Ralph spectrometer will do just...

This video is answering the question of is Pluto a dwarf planet.

Permanently shadowed regions capable of accumulating surface ice were identified in the northern hemisphere of Ceres using images taken by NASA’s Dawn mission combined with sophisticated computer modeling of...

I'm sure most of us grew up with the knowledge that Pluto was our solar system's ninth planet. So what changed about the definition?

NASA's Dawn spacecraft is currently on its way to the asteroid belt where it will eventually meet with Ceres, its largest celestial body. The dwarf planet has an average diameter of about 950 km (590 miles). Dawn captured the first image...

Apart from all the planets in the solar system, we've discussed smaller objects as well, like asteroids and comets, and also dwarf planets. While Pluto is the most famous dwarf planet, Eris is actually slightly more massive, making it...

This video looks at the characteristics of the outer planets, dwarf planets, moons and comets.

The New Horizons probe reached its closest approach to Pluto on July 14, 2015 at 7:49 EST. We have received more and more detailed images and data about the dwarf planet and its largest moon, Charon. Very exciting times!

This live-action video program is about the term solar system. The program is designed to reinforce and support a student's comprehension and retention of the term solar system through use of video footage, photographs, diagrams and...

We've just wrapped up a survey of all the planets and moons in the solar system. But is that all there is? Not even close! There are tons of objects that make up the asteroid belt, the Kuiper belt, the Oort cloud, you can't even believe...

In this video, Relevart, an alien, visits Earth and teaches a young Earthling named Will the Alphabet. They embark on a journey through space, exploring various celestial objects and learning about them. The video combines educational...

What would it be like to land on Pluto? NASA has just released a video, based on photos taken by the New Horizons spacecraft during its historic encounter with the dwarf planet.



The frames show actual...

At the distance of Pluto, the Sun appears about 1000 times fainter than on Earth. Pluto has an eccentric orbit averaging some six billion kilometres from the Sun. After its discovery in 1930 Pluto was considered the ninth planet, but the...

Until 2006 it was classified as a planet. Pluto has one large moon, Charon, and two smaller moons, Nix and Hydra, which cross the view in that order. In this alignment, Pluto's shadow falls directly on Charon and, half an orbit later,...
