Solar system with seven planets and a sun found

20 posts in this topic

A solar system containing up to seven planets orbiting a sun-like star has been detected 127 light years from Earth.

The planetary system is believed to be the largest ever discovered beyond the sun.

Astronomers have confirmed the presence of five planets and have tantalising evidence of two more.

The distance of the planets from their parent star follow a regular pattern, similar to that seen in our own solar system.

'We have found what is most likely the system with the most planets yet discovered,' said Dr Christophe Lovis, who led the European Southern Observatory (ESO) scientists.

'This remarkable discovery also highlights the fact that we are now entering a new era in exoplanet research: the study of complex planetary systems and not just of individual planets.

'Studies of planetary motions in the new system reveal complex gravitational interactions between the planets and give us insights into the long-term evolution of the system.'

The parent star, known as HD 10180, lies in the southern constellation of Hydrus 127 light years away.

Astronomers patiently studied it for six years using a planet-finding instrument called the HARPS spectrograph, attached to ESO's 3.6 metre (11.8ft) telescope at La Silla, Chile.

From 190 individual HARPS measurements, they were able to detect tiny wobbles in the star's motion caused by the gravitational tugs of its planets.

The five strongest signals corresponded to planets with Neptune-like masses, between 13 and 25 times that of the Earth.

These planets, with orbit periods ranging from six to 600 days, are separated from their star at 0.06 to 1.4 times the distance between the Earth and sun.

Dr Lovis added: 'We also have good reasons to believe that two other planets are present. One would be a Saturn-like planet (with a minimum mass of 65 Earth masses) orbiting in 2,200 days. The other would be the least massive exoplanet ever discovered, with a mass of about 1.4 times that of the Earth.

'It is very close to its host star, at just two per cent of the Earth-sun distance. One 'year' on this planet would last only 1.18 Earth days.'

The planet would be rocky, like the Earth, but probably far too hot to sustain life.

With at least five Neptune-sized planets circling inside an orbit equivalent to that of Mars, the HD 10180 system has a more populated inner region than our solar system.

So far astronomers have found 15 systems containing at least three planets.

The last record holder was 55 Cancri, which has a total of five planets including two gas giants.

Details of the discovery were presented today at an exoplanet meeting at the Haute-Provence Observatory in south-east France.

They need 4 telescopes each the size of hubble, in space to focus on the stars to actually see the planets.

thought this pic i see the other day was pretty sick.

Absolutely amazing. Just a matter of time before they find a planet with life.

they have found quite a few planets that could harbour life, some of them a bit earth like aswell i think.

but i dont think life would be found first outside of the solar system. its just a lot harder to try to analyse something so far away and find concrete proof from telescope analysis alone. its far more likely that probes going to Europa, Triton and the other moons of the solar system will turn up with evidence of life. especially on Europa, i think its just a matter of time before microbial life is found there at least.

find it kinda hard sometimes to actually contemplate what these pictures show

in all the vastness of space it must be mathematically certain that there is life out there. but whether we will ever experience it, i doubt it.

Just makes me wonder wtf I am doing.

Seriously why are we here? Like, what made all these planets? I just don't get it. I can't comprehend the size of things being hundreds of times the size of earth.

Exactly.

Crazy stuff.

Its mad how we humans are so small in comparison to the universe etc but yet we are quite aware to an extent of how small we are.

Humand minds = powerful.

Good thread

love this stuff

i recently watched

trust

i really hope we get to have another life cos id hate to miss out on whats coming up in the next couple hundred years

also hope i dont come back as a woman or an animal

I think this sometimes but then again, thinking that often leads to thinking allow being around when one of the following happens

Sik. There must be other life out there but it probably ain't sumthing that looks anything lyk humans or animals. I think we exist only n this planet because its the perfect environment. yo i hope when u die all this sh*t gets explained!

it would be amazing where just before you die you have that moment of clarity where everything you ever wanted to know about anything is explained.
