Two Giant Planets, Companion Star Discovered In Known Planetary System
2013-01-25 09:56:36

Lee Rannals for redOrbit.com — Your Universe Online Astronomers discovered that the HAT-P-7 planetary system includes at least two giant planets and one companion star. The discovery of a previously unknown companion, HAT-P-7B, to the central star, HAT-P-7, as well as confirmation of another giant planet, HAT-P-7c, orbiting outside of the retrograde planet HAT-P-7b offers up new insights into how such planets may form. Astronomers used the Subaru Telescope to discover the first...

Uranus' Bumpy Ride
2011-10-06 08:41:52

Uranus´s highly tilted axis makes it something of an oddball in our Solar System. The accepted wisdom is that Uranus was knocked on its side by a single large impact, but new research to be presented on Thursday 6th October at the EPSC-DPS Joint Meeting in Nantes rewrites our theories of how Uranus became so tilted and also solves fresh mysteries about the position and orbits of its moons. By using simulations of planetary formation and collisions, it appears that early in its life...

A team of scientists has found a new planet which orbits the wrong way around its host star. The planet, named WASP-17, and orbiting a star 1000 light years away, was found by the UK's WASP project in collaboration with Geneva Observatory. The discovery, which casts new light on how planetary systems form and evolve, is being announced today (12th August) in a paper submitted to Astrophysical Journal. Since planets form out of the same swirling gas cloud that creates a star, they are expected...

Retrograde Motion -- Retrograde motion is the orbital motion of a body in a direction opposite that which is normal to spatial bodies within a given system. 'Retrograde' derives from the Latin words retro, backwards, and gradus, step. In the Solar system, mostly everything rotates in the same sense: all major planets orbit the Sun counterclockwise as seen from the pole star (Polaris). Most planets spin in the same sense, including Earth. The same happens with the orbital motions of the...

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 Ananke, Carme, Pasiphae and Sinope and Saturn's moon Phoebe also orbit retrograde, but all of them...
