The researchers mathematically showed that the same mechanism that forces the binary together shifts the alignment
of the circumbinary planet, potentially allowing it to sneak far enough away to escape incineration.
Since the novel was for the first time published in 1961, it precedes Star Wars» Tatooine planet (1977) in terms of the first case
of a circumbinary planet in pop culture.

of one, for example, or compact multi-planet systems.
The worlds are aptly named «
circumbinary planets» («circum» meaning around, and «binary» referring to two objects), and in this type
of binary system, the two stars orbit each other while the
planet orbits the two stars (pictured above).

The trio is not the only so - called
circumbinary system known, but it is the first for which researchers have been able to measure the properties
of both stars and the
planet so precisely, and the first system where the
planet has been directly detected, rather than inferred.

Based on these conclusions for Kepler - 34, it seems likely that all
of the currently known
circumbinary planets have also migrated significantly from their formation locations — with the possible exception
of Kepler - 47 (AB) c which is further away from the binary stars than any
of the other
circumbinary planets.
In any case, a
circumbinary orbital distance from CM Draconis Aab where an Earth - type
planet would be comfortable with liquid water would be centered around 0.3 AU, with a «year»
of 18 to 35 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...
So - called
circumbinary planets — those
planets that orbit around a binary star, like the fictional Tatooine from the Star Wars — can be ejected off into space as a consequence
of their stars» evolution, according to a new study to be published in the Astrophysical Journal (arXiv.org preprint).
Planets like Kepler - 1647b in orbit around binary stars are known as circumbinary planets, and planet hunters spot them by looking for a dimming in the light from a star as the planet transits, or passes in front of the star from our persp

Kepler - 16b was the Kepler telescope's first discovery
of a
planet in a «
circumbinary» orbit — circling both stars, as opposed to just one, in a double - star system.
