A more appropriate way to put this might be that life will emerge on
small rocky planets with a probability of 1 per cent.
It speculates that 1 per cent
of small rocky planets are «habitable» and continues as if life has inevitably emerged on them.
The Kepler 90 solar system is like a cinched - up version of our own:
Small rocky planets hug the star most tightly, while larger planets hang back.
The basic architecture of our solar system, where things go in circles, and there are
small rocky planets close to the sun and big massive gas giants far from the sun, is certainly not the only architecture.
In the Solar System,
small rocky planets such as the Earth orbit near the Sun, whereas gas giants like Jupiter and Saturn are found much further out.
Stars A and B were selected as two of the top 100 target stars for NASA's indefinitely postponed Terrestrial Planet Finder (TPF) to directly
image small rocky planets in Earth - type habitable orbits.
Kepler is capable of detecting the ~ 0.01 % decrease caused
by small rocky planets and potentially Earth - like planets.
They hope it will open up the world of super-Earths, relatively unfamiliar objects between the size
of small rocky planets and gas giants, of which we have no examples in our solar system.
Adrift on one
small rocky planet that orbits one ordinary star out of a trillion trillion stars in the observable universe, each one of us is locked inside a singular, self - aware speck of flesh, embedded in a web of biological evolution that sprawls across the eons.
The results are beginning to show that
small rocky planets are the most common of all planet types in the catalog, making up as much as 25 %.
The spacecraft is expected to scan the sky to look for
both small rocky planets and large gas giants, as well as everything in between, around some 200,000 stars within about 300 light - years from Earth.
We can rule out gas giants at Barnard's Star thanks to continuing Doppler monitoring, but we can't yet rule out
small rocky planets of the kind we are now turning up around other M - dwarfs in data from the Kepler mission.
Although also a super-Earth class planet, Kepler - 10b has only 1.4 times Earth's radius and has been determined to be one of
the smallest rocky planets detected thus far.
Sen — One of the overarching goals of extrasolar planet detection is to find out if other planetary systems look like our own Solar System, complete with
small rocky planets, large gas giant planets, and hundreds of small moons.
