In 2018, just next year folks, let's hope, NASA is going to be launching its James Webb Space Telescope, a giant piece of kit that's going to be about one and a half million kilometers out there beyond the orbit of the moon, and it's going to be able to look at these planets as they transit across the face of the star.

With planets orbiting M dwarfs quickly becoming the darlings in the search for life beyond our solar system, a new generation of observatories are poised to discover hundreds of worlds around these stars.

In space, above our atmosphere, stars do not twinkle; in space a telescope is also beyond day and night and can thus stare at the same star for weeks on end, gradually teasing from its light the barely perceptible but regular flickers caused by a small orbiting planet.

This scenario naturally produces a planetary system just like our own: small, rocky planets with thin atmospheres close to the star, a Jupiter - like gas giant just beyond the snowline, and the other giants getting progressively smaller at greater distances because they move more slowly through their orbits and take longer to hoover up material.

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).

Among several scenarios to explain Fomalhaut b's 2,000 - year - long orbit is the hypothesis that an as yet undiscovered planet gravitationally ejected Fomalhaut b from a position closer to the star, and sent it flying into an orbit that extends beyond the dust belt.

In the research of extrasolar planets, astronomers have found a wide variety of planets such as Jupiter - like gaseous giant planets circling around central stars in a much smaller orbit than that of the Mercury, and planets that have a very large orbit far beyond the Neptune's orbit.

GJ 1214 is a red dwarf star with one known planet in a hot inner orbit, beyond even the inner edge of the star's close - in habitable zone, as imagined by Aguilar with two hypothetical moons (more).

Given the large orbital eccentricities of these two objects (which move beyond 500 AUs of the Sun), some astronomers have argued that they were likely to have been strongly perturbed by a massive celestial object (which is unlikely to have been Neptune as they do not come close enough to feel its gravitational influence) such as the passing of a rogue planet (perturbed from its primordial orbit by the gas giants of the inner Solar Sylstem) or one or more passing stars, which could have dragged the two objects farther out after initial orbital perturbation by Neptune or as part of a «first - generation» Oort Cloud.

Over the past several years, however, thousands of planets have been discovered orbiting stars beyond our sun, allowing us to study our own Earth in the context of other worlds for the first time in history.

A rogue planet moving through the solar system would be pretty obvious to astronomers, who can detect planets far beyond our home solar system by looking for the wobbles their passage causes in the stars they orbit.
