Apostolos Christou reports on a new model to explain the two “oddball’’ moons of Neptune: Triton, a >2000 km diameter satellite that circles Neptune in the opposite direction that the planet rotates; and 300-km Nereid, the planetary moon with the most elongated orbit in the solar system....
1. What could indicate the existence of the ninth planet? 2. How big is the new planet thought to be? 3. Why are astronomers taking the idea that there is another planet in the Solar System seriously? 4. What happened to Pluto in 2006?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. The solar system stretches outward from the sun, passing the four inner planets, thro...

cross through our planet's atmosphere each day. Astronomers have recorded more than 800 comets passing through the inner part of the solar system. Billions more, however, lie in the area surrounding the solar system, in the far reaches of the swarm of comets known as the Oort cloud or in...
The scramble to find a new planet mnemonic is just the tip of the iceberg when it comes to learning and understanding what makes up our solar system. In the old days, prior to spacecraft exploration and high-resolution cameras on both space-based observatories (such asHubble Space Telescope)...
