Latest Eris Stories
New observations using three telescopes at the European Space Observatory's (ESO) Chile location have shown that the dwarf planet Makemake does not have much of an atmosphere after all.
The European Southern Observatory announced on Wednesday that astronomers have accurately measured the diameter of the dwarf planet Eris for the first time.
The bizarre, hourglass-shaped Kuiper belt object 2001QG298 spins round like a propeller as it orbits the Sun, according to an astronomer from Queens University Belfast.
Scientists have discovered that a dwarf planet at the edge of the solar system, dubbed 2007 OR10, is an icy world with about half its surface covered in water ice that once flowed from ancient, slush-producing volcanoes.
The fifth dwarf planet of the Solar System, Haumea, and at least one of its two satellites, are covered in crystalline water-ice due to the tidal forces between them and the heat of radiogenic elements.
In the outer reaches of our solar system lies a mysterious region far more remote and difficult to explore than the Australian outback.
A planet about eight times the mass of Jupiter has been confirmed to orbit a Sun-like star that's some 300 times farther from its own star than Earth is from its sun.
A dark red area discovered on dwarf planet Haumea appears to be richer in minerals and organic compounds than the surrounding icy surface.
RMI's Energy and Resources Team (ERT) implements advanced resource planning process that helps guide energy investment options that are sustainable and cost-effective. SNOWMASS, Colo., March 2 /PRNewswire-USNewswire/ -- Rocky Mountain Institute (RMI) today published its Energy and Resource Investment Strategy (ERIS), a breakthrough approach to energy planning.
Quaoar -- Quaoar ("kwah-oh-ahr", /kwA o Ar/) is a Trans-Neptunian object circling the Sun in the Kuiper belt, discovered in 2002 by astronomers Chad Trujillo and Mike Brown at the California Institute of Technology in Pasadena, California. Quaoar is estimated to have a diameter of about 1,280 kilometres, which would make it the largest Solar System object discovered since Pluto and, indeed, the largest known minor planet. Larger than all the asteroids put together, it is about one...
Planet Charon -- Charon is the only known satellite of Pluto. Charon was discovered by astronomer James Christy in 1978 using photographic plates which showed a bulge moving around Pluto. Christy named it after the Greek mythological figure Charon but pronounced it differently. The "ch" at the beginning of the moon's name is soft so it sounds like "Sharon," after the astronomer's wife Charlene, nicknamed Char, which both have soft ch sounds. The mythological figure's name is...
Planet Pluto -- Pluto is the ninth and smallest planet of our solar system. It was discovered by the astronomer Clyde Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 (although the body was first photographed on March 19, 1915). Tombaugh was searching for a "Planet X" to explain the orbit of Neptune; further analysis, with seven decades more data about Neptune's position, has resolved the perceived anomaly without need for an additional gravitational pull on Neptune....
