For decades we have blindly checked the sky overhead or targeted stars that are old enough, metallic enough and stable enough to have rocky planets in the right orbits.

In our universe the laws of physics seem precisely calibrated to allow the existence of long - lived stars, planets with stable orbits, and molecules that allow complex chemistry.

The new planets completely fill up the habitable zone of Gliese 667C, as there are no more stable orbits in which a planet could exist at the right distance to it.

They eliminated those with orbital radii less than one tenth that of Earth's, because at that distance moon systems might not remain in stable orbits around their planets on billion - year timescales.

He pointed out that there are many close - orbiting planets around middle - aged stars that are in stable orbits, but his team doesn't know how quickly this young planet is going to lose its mass and «whether it will lose too much to survive.»

An Earth - type planet could have liquid water in a stable orbit centered around 0.036 AU from Star B — well within the orbital distance of Mercury in the Solar System.

If so, then conditions would be more favorable for the existence of stable orbit for an Earth - like planet (with liquid water) centered around 1.5 AU from around Iota Persei — around the orbital distance of Mars in the Solar System.

Recent numerical integrations, however, suggest that stable planetary orbits exist: within three AUs (four AUs for retrograde orbits) of either Alpha Centauri A or B in the plane of the binary's orbit; only as far as 0.23 AU for 90 - degree inclined orbits; and beyond 70 AUs for planets circling both stars (Weigert and Holman, 1997).

An Earth - type planet could have liquid water in a stable orbit centered around 1.18 AU from Star A — between the orbital distances of Earth and Mars in the Solar System.

For an Earth - type planet around HD 189733 A to have liquid water at its surface, it would need a stable orbit centered around 0.5 AU — between the orbital distances of Mercury and Venus in the Solar System (with an orbital period around 150 days assuming a stellar mass around 82 percent of Sol's.

If a small, rocky planet can develop without the interference of planet b, then stable orbits appear to be possible in the inner portion of the habitable zone (Noble et al, 2002, in pdf; and Jones and Sleep, 2003).

If so, then conditions would be more favorable for the existence of stable orbit for an Earth - like planet (with liquid water) centered around 1.15 AU from around 15 Sge — between the orbital distances of Earth and Mars in the Solar System.

Assuming that the spectroscopic companion B does not preclude a stable inner planetary orbit, the distance from Star A where an Earth - type planet would be «comfortable» with liquid water is centered around only 0.457 AU — between the orbital distances of Mercury and Venus in the Solar System.

If so, then conditions would be more favorable for the existence of stable orbit for an Earth - like planet (with liquid water) centered around 1.12 AU from around 37 Gem — between the orbital distances of Earth and Mars in the Solar System.

They remain in stable orbits either leading or following the planet in its own orbit, 60 degrees before or after the planet.

An Earth - type planet could have liquid water in a stable orbit centered around 3.5 AU (within a predicted habitable zone ranging between 2.3 and 4.8 AUs) from Star A — between the orbital distances of the Main Asteroid Belt and Jupiter in the Solar System (NASA Stars and Exoplanet Database).

Orbity.io is a tricky and very addictive massively multiplayer browser based rocket game in which players attempt to maintain stable orbits around the planet Earth for as long as possible or take off and explore space.
