Four planets orbiting star HR 8799
Infrared images of four recently discovered planets appear as white dots circling the star HR 8799. The four planets are roughly the size of Jupiter - each one is approximately five to seven times the mass of Jupiter. The video displays 7 years of orbital movements. This system is larger than our solar system, but it is much younger, only 30 million years old instead of 4.6 billion years for the solar system. The star HR 8799 and four planets shown in the video lie about 130 light years away from Earth, in the direction of the constellation Pegasus. The data was collected over seven years using the Keck Observatory in Hawaii.
Organizations that contributed to this project include the National Research Council of Canada, University of California Berkeley, NExSS and the W. M. Keck Observatory.
