The giant planets will remain a puzzle for a long time. 4. The giant planets, with such feeble solar heating, are also very cold. 5. The high abundances of hydrogen and helium are features of the giant planets also. 6. An orbiting infrared survey telescope, able to scan the entire sky, would be the best bet for finding a giant distant planet. 7. Astronomers reported Friday that they have discovered another tiny moon of the giant planet Jupiter. 8. Astronomers suspect that these giant planets are, like Jupiter and Saturn, huge spheres of gas without a solid surface. 9.
