Can you prove that orbiting a few thousand of those trillion trillion stars there aren't other planets on which he has also created life?

Very few planets in clusters are known and this one has the additional distinction of orbiting a solar twin — a star that is almost identical to the Sun in all respects.

These are examples of planets that orbit their host star in 25 days or fewer, and as a side effect have one side permanently facing their star, and the other side permanently facing away.

But astronomers have always wondered about the paucity of close - in brown dwarfs: While many giant planets have been found in small orbits, whirling around their sunlike stars in just a few days, the more massive brown dwarfs appear to shun these intimate relationships.

Over the past few years, ground - based telescopes have discovered a dozen stars that might be accompanied by Jupiter - size planets, some of which are broiling in orbits tighter than Mercury's.

A few of the planets orbiting a star called TRAPPIST - 1, which is 40 light years away, have shown another sign they might be right for life: water.

The idea that there might be another living planet a few light years from home, orbiting a star visible with the naked eye, is a tantalising prospect.

In a few other cases a candidate planet had been observed near a star but had not been proved to follow a planet - like orbit.

The discovery of planets orbiting other stars has made headlines in the past few years.

That's the conclusion of a new simulation, which helps explain why older stars tend to have few planets orbiting close to them.

What is more, improved technology should also allow larger observatories such as Keck to move from the few giant planets already imaged — all of which orbit their host stars at relatively large distances — to closer - in worlds more like our own.

Only a few years ago, detecting exoplanets — planets that orbit distant stars — was done only at professional observatories.

Relatively few giant planets orbiting low - mass stars are known, so every instance is of interest to planet hunters.

Earlier this year the scientists of NASA's Kepler mission announced that their planet - hunting space telescope had identified more than 1,200 possible exoplanets (worlds orbiting stars other than our own sun) in its first few months on the job.

Borucki says it will be a few years yet before Kepler is able to identify a true Earth analogue — a small planet on a one - Earth - year orbit around a sunlike star.

From even just a few light - years away in our own little corner of the Milky Way, a planet in an orbit comparable to Earth's would be too close to its star for even the Hubble to see them as two distinct objects.

Leslie Sage, an authority on exoplanets (planets outside our Solar System), was perplexed when he learned about hot Jupiters — Jupiter - size planets orbiting so close to their stars that they complete an orbit every few days.

The findings help explain why astronomers have detected few circumbinary planets — which orbit stars that in turn orbit each other — despite observing thousands of short - term binary stars, or...

Moreover, at least 150 extrasolar planets have been identified in the last few years, suggesting that life - hospitable planets orbit most stars.

It's possible that instead of forming as terrestrial planets in place, rocky planets orbiting their stars every few days formed further out beyond the snow line where they accreted large amounts of gas before migrating and being stripped of their atmospheres.

«And because these planets orbit brighter stars, we'll be able to more easily study everything possible about them, whether it's measuring their masses with Doppler spectroscopy — already underway at Keck Observatory and APF — or measuring their atmospheric makeup with the James Webb Space Telescope in just a few years.»

Hot Jupiters are heated gas giant planets that are very close to their stars, just a few million miles distant and orbiting their stellar hosts in just a few days.
