This is a picture made by an artist to show what the Jupiter-like planet orbiting the star, 55 Cancri, might look like. We do not have photographs of the planet. It is about forty-one light years away from Earth. The artist added a small moon to the picture although no moon has been found.

An Exoplanet that Looks Like Jupiter!
News story originally written on June 18, 2002

A team of astronomers, who have been peering into the skies for many years, announced that they have found 13 planets outside our solar system called exoplanets. This brings the total number of known exoplanets to over 90!

The team is very excited about one of their discoveries. An exoplanet orbiting a star called 55 Cancri, within the Cancer constellation, is very different from any of the others that have been found. Dr Marcy, a leader of the research team, described that, ďall other extrasolar planets discovered up to now orbit closer to the parent star, and most of them have had elongated, eccentric orbits. This new planet orbits as far from its star as Jupiter orbits from the Sun.Ē

Jupiter is about four and a half times further from the Sun than Earth and takes about 12 years to complete one orbit around the Sun. The new planet is a similar distance from its star and takes 13 years to complete one orbit around the star.

The new planet is not exactly like Jupiter, however. It is much more massive than Jupiter. Its orbit is different than Jupiterís orbit, taking an oval-shaped route around the star instead of a more circular route. Even though the new planet is not exactly like Jupiter, they are similar enough that the research team is hopeful that we may someday find more exoplanets that are like planets in our own solar system.
