 Scientists discover dwarf planet 'Makemake' sans atmosphere

 

Astronomers have discovered that about two-thirds the size of Pluto the dwarf planet, is the lack of atmosphere.
Pluto is a planet way round, but after that Eris, the solar system's most massive known dwarf planet closest to the sun in the 'Makemake' journey around the sun.
The last comments showed that chilly Makemake with her as dwarf planets, some astronomers that environment, if the expected, like Pluto are leading.
But a new study Jose Luis Ortiz (Instituto de Astrofisica de Andalucia, CSIC, Spain) led by astronomers felt like the Eris, Makemake is surrounded by an environment.
Very large telescope (VLT), new technology (NTT) of the telescope and TRAPPIST (TRAnsiting planet and PlanetesImals small telescope) - European Southern Observatory more than one (ESO) La Silla and Paranal in Chile with three telescopes using sites Comments of the joint team - along with other small telescopes in South America Makemake look at the data passed in front of the star.
Makemake is passed in front of the star blocked out, star disappeared and reappeared very suddenly, but gradually brightening and fading out. This means that this small dwarf planet has no significant atmosphere, "said Jose LUIS Ortiz.
"They thought it was a good opportunity to create a climate of Makemake - a sign that all is one that shows how far we learn about these mysterious bodies Makemake features for the first time I know the feeling icy dwarf planet club's chosen major step forward in our study, "Jose LUIS Ortiz said in a statement.
Team a more detailed view of new comments Add Makemake - The most accurate way to determine the size, can put constraints on the environment and the intensity of dwarf planet for the first time estimates.
The albedo - they also astronomers measure how much light the surface reflects the sun Makemake is allowed.Makemake albedo of 0.77 dirty ice, Pluto higher, but less than that of Eris.
It is only possible to see this kind of detail Makemake he passed in front of a star - a spectacular event known as occultation.
Occultations Makemake is a particularly unusual because of the relatively few stars in the sky move into an area. Accurately predict and rare events are difficult to identify.
Pluto, Eris, and the examples orbiting our sun among several glacial period are Makemake, "said Jose LUIS Ortiz.
will be able, ".
Makemake still five dwarves Astronomy recognized by the International Union of Planets is one. Others Ceres, Pluto, Haumea and Eris are.
