32 new Planets are discovered in 2009
The smallest is five times the size of the earth

HD 80606 b is a superjovian planet (Eccentric Jupiter) 190 light-years distant in the constellation of Ursa Major. The planet was discovered orbiting the star HD 80606 in April 2001 by a team led by Michel Mayor and Didier Queloz. Based on its mass, at 4 times that of Jupiter, it is a gas giant. Since the planet transits its star, its radius is determined to be at 73,560 km (slightly larger than planet Jupiter).
The planet has wild variations in its weather as it orbits its parent star. Computer models predict the planet heats up 555 °C (1,000 °F) in just a matter of hours triggering "shockwave storms" with winds that move faster than the speed of sound
European astronomers have up till now discovered 32 previously unknown plants orbiting other stars than our own sun. The number of eksoplanets is then up to over 400 at the moment.
The smalles of the newly discovered eksoplanets is around 5 times the size of the earth, while the largest is around 5 times larger than our solar system planet Jupiter which is the largest plant in our own solarsystem.
This was revealed at a statement given by the European Space Agency astronomers this Monday.
The astronomers stated that more than 40 percent of the stars looking like our own sun have planets with small masses.
The new observations have given the astronomers a large insight into the variety of planet systems. Nuno Santos, one of the project researchers stated that this helps us to understand how planets are formed- De nye observasjonene har gitt astronomene stor innsikt i planetsystemets mangfold.
The astonomers used HARPS, which is a special designed instrument at the European observatory in Chile to map the new eksoplanets.
This instrument gives the researchers the chance to calculate the size and mass of objects observed and discovered in the Universe.
HARPS is a spectrometer dedicated to the search for extrasolar planets by means of the technique of precise radial velocity measurement. HARPS is developped by a consortium headed by the Geneva Observatory. It is installed at the Coude room of the 3.6 meter telescope at La Silla, with an optical fiber link to the Cassegrain focus.
