SWEEPS-11 is an extrasolar planet
orbiting the star
SWEEPS J175902.67−291153.5 in the constellation
Sagittarius
approximately 22000 light years away from the Solar System
(based on a distance modulus
of 14.1). This planet was found in 2006 by the Sagittarius Window Eclipsing Extrasolar Planet Search
(SWEEPS) program that uses transit method.
This hot Jupiter
has a mass 9.7 times that of Jupiter
and a radius of 1.13 times Jupiter. The planet orbits at about 1.75 times closer to the star than 51 Pegasi b
is to 51 Pegasi
, taking only 1.8 days or 43 hours to revolve around the star.
Extrasolar planet
An extrasolar planet, or exoplanet, is a planet outside the Solar System. A total of such planets have been identified as of . It is now known that a substantial fraction of stars have planets, including perhaps half of all Sun-like stars...

Star
A star is a massive, luminous sphere of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth...

Solar System
The Solar System consists of the Sun and the astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. The vast majority of the system's mass is in the Sun...
