Iota Horologii b
Iota Horologii b (ι Hor b / ι Horologii b), often catalogued HR 810 b, is an extrasolar planet approximately 56.5 light-years away in the constellation of Horologium (the Pendulum Clock). Iota Horologii b has a minimum mass 1.94 times that of Jupiter, however preliminary astrometric measurements suggest that the object may be around 24 Jupiter masses and would therefore be a brown dwarf.
Detection and discovery.
The discovery of Iota Horologii b was the result of a long-term survey
from the Sun) to just outside the orbit of the Earth (at 162 million km or 1.08 AU). Because the planet is at least 720 times more massive than the Earth, it is predicted that Iota Horologii b is more similar to planet Jupiter.
Because Iota Horologii is younger than the Sun, the announcement latter retracted of a protoplanetary disk caused speculation of this system still being active in debris bombardment.
In recent astrometric analysis of Iota Horologii b suggests that planet b may have as much as 24 times
