  2. The eighth planet from the Sun, Neptune is considered an ice giant because it is largely made up of water, ammonia, and methane in solid form. As our solar system took shape about 4.5 billion years ago, Neptune was likely formed in a massive, ancient cloud of gas, dust, and ice which collapsed into a spinning disc with our Sun at its centre.
  3. Neptune is the windiest planet with clouds of frozen methane that travel at speeds up to 2,000 kilometres per hour, which is three times stronger than Jupiter's winds. Neptune has 14 moons. The largest moon, Triton, orbits retrograde in the opposite direction of Neptune's rotation. Neptune is the only planet in our solar system discovered using ...

  5. Gas planets may have a rocky core, but are mostly made up of huge quantities of gases like hydrogen, helium and methane. They are much bigger than rocky planets. An exoplanet is any planet orbiting a star that is not the Sun. Examples. Our solar system contains eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
  6. When Pluto was discovered in 1930, it was called the ninth planet in our solar system, but its status as a fully fledged planet came into question in the 1990s. Pluto was officially reclassified as a dwarf planet in 2006. The best-known dwarf planet, Pluto is also the largest in size and the second largest in mass. Pluto has five moons.
  7. 2022-09-21 - Webb's Near-Infrared Camera (NIRCam) image of Neptune, taken on July 12, 2022, brings the planet's rings into full focus for the first time in more than three decades.<p>The most prominent features of Neptune's atmosphere in this image are a series of bright patches in the planet's southern hemisphere that represent high-altitude methane-ice clouds. More subtly, a thin ...

  9. Researchers are able to take incredible pictures of the planets in our solar system using powerful telescopes and space probes. But exoplanets, which orbit distant stars, are more difficult to directly observe, because they are much farther away and close to their extremely bright stars.Instead, astronomers often detect exoplanets indirectly, through the effect they have on their host star.
  10. Astronomical objects can sometimes be difficult to categorize. For example, the difference between an asteroid and a planet can be hard to define, so scientists created a new category of objects, dwarf planets, to bridge the gap.The "grey zone" in what counts as a giant planet versus a small star is similarly complicated - brown dwarfs exist in that in-between.
