10199 Chariklo (1997 CU26)

Chariklo is a dwarf planet with an orbit between Jupiter and Neptune. NASA JPL has not classified Chariklo as potentially hazardous because its orbit does not bring it close to Earth.

With a diameter of about 188 miles (302 kilometers), Chariklo is the largest member of an asteroid class known as the Centaurs.

Uranus, Neptune and even Jupiter has rings, too, but so does a tiny world over two billion miles away from Earth called 10199 Chariklo—as now proven by the James Webb Space Telescope.

On Oct. 18, 2022, researchers used JWST to observe the rings around Chariklo, which belongs to a mysterious class of solar system objects called centaurs. These hybrid objects skirt the line between asteroid and comet, typically behaving like comets while having surfaces that more closely resemble those of asteroids.

Chiron lived predominantly on Mount Pelion; there he married the nymph Chariclo who bore him three daughters, Hippe (also known as Melanippe meaning the "black mare" or Euippe, "good mare"), Endeïs, and Ocyrhoe, and one son Carystus.

Little asteroid-like Chariklo – which orbits the sun between Saturn and Uranus – was discovered in 2013 to have two thin rings. Now researchers have proposed the existence of a tiny, unseen moon orbiting Chariklo, which might help maintain and shape the rings.

At a distance of just 63 light years, HD 189733b is the closest hot Jupiter to Earth, which makes it a prime target for astronomers who want to learn more about this type of exoplanet and the atmosphere around it.

The average distance between the Earth and the Moon is 384 400 km (238 855 miles). The Moon's elliptical orbit with the distances at apogee and perigee.

Auahitūroa is a male Māori deity, personification of comets, and the origin of fire.

The origin of the rings is unknown, but both are likely to be remnants of a debris disk, which could have formed via an impact on Chariklo, a collision with or between one or more pre-existing moons, tidal disruption of a former retrograde moon, or from material released from the surface by cometary activity or ...

Is Halley's comet rare? ›

Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, appearing every 72–80 years. It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061.

Pluto was long considered our ninth planet, but the International Astronomical Union reclassified Pluto as a dwarf planet in 2006. NASA's New Horizons was the first spacecraft to explore Pluto up close, flying by in 2015.

Ceres (minor-planet designation: 1 Ceres) is a dwarf planet in the middle main asteroid belt between the orbits of Mars and Jupiter. It was the first known asteroid, discovered on 1 January 1801 by Giuseppe Piazzi at Palermo Astronomical Observatory in Sicily, and announced as a new planet.

Dwarf planet Ceres is the largest object in the asteroid belt between Mars and Jupiter, and it's the only dwarf planet located in the inner solar system. It was the first member of the asteroid belt to be discovered when Giuseppe Piazzi spotted it in 1801.

Our solar system has five dwarf planets. In order of distance from the Sun they are: Ceres, Pluto, Haumea, Makemake, and Eris.
