This is a picture made by an artist to show what the 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 scientists found 13 planets that are outside our solar system. Because these planets are outside our solar system, they are called exoplanets. One of these exoplanets is special because it may be somewhat like Jupiter. It is orbiting around a star in the Cancer constellation.
Most exoplanets are very close to a star and make small circles as they orbit around the star. This planet is special because it is far away from its star and takes a long time to orbit around it, just like Jupiter.
Jupiter is more than four times further from the Sun than Earth and it takes Jupiter about 12 years to complete one orbit around the Sun. The new planet is a about the same distance from its star and takes 13 years to orbit around the star.
But the new planet is not exactly like Jupiter. It is much more massive than Jupiter and its orbit is a different shape than Jupiterís orbit. The new planet follows a path shaped like an oval as it orbits around the star. The shape of Jupiterís orbit is more like a circle.
Including the 13 exoplanets that this team of scientists just found, there are now more than 90 known exoplanets! The team hopes that they will someday find more exoplanets that are like the planets within our solar system.
