Assume, instead, that many systems start with two Jupiter-size planets in fairly close proximity.

They continue to search for low-mass stars, Jupiter-size planets and other faint objects, which they think may be littering the outer edges of galaxies.

Moreover, as in our own solar system, there are larger Jupiter-size planets orbiting Gliese 876 at greater distances.

These could reveal the transit of a Jupiter-size planet at Jupiter distances across the face of the star.

That, they said, could be the signature of three Jupiter-size planets going to their doom.

HD 205739 b is a Jupiter-size planet.

Of the more than 80 giant objects that have recently been found orbiting nearby stars, most have been estimated to be Jupiter-size planets.

The star the Americans found is accompanied by one and probably two Jupiter-size planets at closer distances than Mercury is from the Sun.

Last year, astronomers reported the discovery of several Jupiter-size planets at Jupiterlike distances from their stars.

However, during the process of migrating into a habitable zone, a Jupiter-size planet may capture a terrestrial planet as a moon.
