Planetary Ring
2004-10-19 04:45:42

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but...

Neptunes Moon Triton
2004-10-19 04:45:41

Planet Triton -- Triton is the planet Neptune's largest moon, discovered by William Lassell in 1846 just 17 days after the planet itself was discovered. It is named after Triton, from Greek mythology. Triton is unique among all large moons in the solar system for its retrograde orbit around the planet (i.e., it orbits in a direction opposite to the planet's rotation). Jupiter's moons...

Neptunes Moon Larissa
2004-10-19 04:45:41

Planet Larissa -- Larissa is the fifth of Neptune's known moons. It was discovered by Harold Reitsema based on ground-based stellar occultation observations, and was photographed by Voyager 2 in 1989. Larissa is irregular (non-spherical) in shape and appears to be heavily cratered, with no sign of any geological modification. Little else is known about it. Since its orbit is below...

Neptunes Moon Galatea
2004-10-19 04:45:41

Planet Galatea -- Galatea is the fourth known moon of Neptune, named after the the Nereid of Greek legend. It was discovered in 1989 by Voyager 2 and very little is known about it. It is irregularly shaped and shows no sign of any geological modification. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to tidal forces and will one day break up into...

Neptunes Moon Despina
2004-10-19 04:45:41

Planet Despina -- Despina is the third known moon of Neptune. It was discovered in 1989 by Voyager 2, and very little is known about it. It is irregularly shaped and shows no sign of any geological modification. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to tidal forces and will one day break up into a planetary ring or impact on Neptune's...

Neptunes Moon Thalassa
2004-10-19 04:45:41

Planet Thalassa -- Thalassa is the second moon of Neptune. Thalassa was named after a daughter of Aether and Hemera from Greek mythology. "Thalassa" is also the Greek word for "sea". It was discovered in 1989 by Voyager 2. It is irregularly shaped and shows no sign of any geological modification. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to...

Neptunes Moon Naiad
2004-10-19 04:45:41

Planet Naiad -- A moon of Neptune, Naiad is named after the Naiads of Greek legend. Naid was the last of the satellites discovered in 1989 by Voyager 2. It is irregularly shaped and shows no sign of any geological modification. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to tidal forces and will one day break up into a planetary ring or impact...

Neptune
2004-10-19 04:45:41

Planet Neptune -- Neptune is the eighth planet from the sun. It is a gas giant. Orbiting so far from the sun, Neptune receives very little heat. Its 'surface' temperature is -218 degrees Celsius (below zero). However, the planet seems to have an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly...

Uranus Moon Puck
2004-10-19 04:45:41

Uranus' moon Puck -- Puck is a moon of Uranus. It was discovered by Voyager 2 in 1986. Little is known about it aside from its orbit, its size, and its dark albedo (approximately 0.07). In Celtic mythology and English folklore, Puck is a mischievous tricky sprite, originally an evil demon, but better known as a character in Shakespeare's Midsummer Night's Dream who travels around the globe...

Uranus Moon Portia
2004-10-19 04:45:41

Uranus' moon Portia -- Portia is a moon of Uranus, named after the 2 two heroines in plays by William Shakespeare. It was discovered in 1986 by Voyager 2. Very little is known about it. Since it is below Uranus' synchronous orbit radius, Portia's orbit is slowly decaying due to tidal forces and it will one day break up into a planetary ring or impact on Uranus' surface. -----...

Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
