WASHINGTON (Reuters) - European researchers said on Monday they discovered a batch of three "super-Earths" orbiting a nearby star, and two other solar systems with small planets as well.


They said their findings, presented at a conference in France, suggest that Earth-like planets may be very common.


"Does every single star harbor planets and, if yes, how many?" asked Michel Mayor of Switzerland’s Geneva Observatory. "We may not yet know the answer but we are making huge progress towards it," Mayor said in a statement.




The trio of planets orbit a star slightly less massive than our Sun, 42 light-years away towards the southern Doradus and Pictor constellations. A light-year is the distance light can travel in one year at a speed of 186,000 miles a second, or about 6 trillion miles.


The planets are bigger than Earth -- one is 4.2 times the mass, one is 6.7 times and the third is 9.4 times.


They orbit their star at extremely rapid speeds -- one whizzing around in just four days, compared with Earth’s 365 days, one taking 10 days and the slowest taking 20 days.

Mayor and colleagues used the High Accuracy Radial velocity Planet Searcher or HARPS, a telescope at La Silla observatory in Chile, to find the planets.


More than 270 so-called exoplanets have been found. Most are giants, resembling Jupiter or Saturn. Smaller planets closer to the size of Earth are far more difficult to spot.

None can be imaged directly at such distances but can be spotted indirectly using radio waves or, in the case of HARPS, spectrographic measurements. As a planet orbits, it makes the star wobble very slightly and this can be measured.


"With the advent of much more precise instruments such as the HARPS spectrograph ... we can now discover smaller planets, with masses between 2 and 10 times the Earth’s mass," said Stephane Udry, who also worked on the study.


The team also said they found a planet 7.5 times the mass of Earth orbiting the star HD 181433 in 9.5 days. This star also has a Jupiter-like planet that orbits every three years.

Another solar system has a planet 22 times the mass of Earth, orbiting every four days, and a Saturn-like planet with a 3-year period.


"Clearly these planets are only the tip of the iceberg," said Mayor.


"The analysis of all the stars studied with HARPS shows that about one third of all solar-like stars have either super-Earth or Neptune-like planets with orbital periods shorter than 50 days.

With Earth Technology now and lets say we have unlimited fuel it would take 450,000 years to get to those Earth type planets I dont think even an person is Immortal would want to go there for free land.

Lol Einstein said you can't travel faster then the speed of light, the fastest thing on Earth is 11 miles per second, we will need to find a wormhole or something that can manipulate stars and space so we will actually survive the trip.

Many a poor people and weak ethnicitys would go there like Black Americans, Africans and Chinese...Lots and Lots of Chinese.

Rich people would visit, and get a house like a second or third house but they would not want to live there because they already have money and power on Earth.

When Cuba was being settled non of the Royal Court of Spain went to live there. They had power in Spain so they stayed in Spain.

You seem to be a bitter boy.

it would be awesome to travel to those planets but with the government corrupting i dont think its going to happen! think about it..... its just wack

theres lack of fuel, lack of knowledge about space, cost of the technology/funding research... too much valuables that needs to be known and plus theres no guarantee that these "super earths" exist

Erm, i shouldn't say who cares because people like you complain and brings more drama and etc.
However, I should say that why bother talking about it? Not like you will be still alive in a million of years.

It sucks that we'll never be able to reach there in our life time. =__=;;
Can you imagine living there? O_O
The days and nights flying by fast.


wait..wouldnt we age faster then?


No.

an experiment on bringing a dozen pairs out there and see if it will work out or maybe a one way ticket

I can see a movie where earth has nearly been destroyed and the people all gather onto spaceships and they live there and keep reproducing until they reach the planet.
