美国航宇局在1973年4月5日发射的先驱者11号空间探测器,经6年多漫长的飞行,行程32亿公里,于1979年9月1日到达土星附近(距离土星云顶20800公里),这时它离地球的距离约为16亿公里。先驱者11号在接近土星的过程中,连续10天对土星进行了拍摄和探测,获得了大量的资料。下面简要介绍先驱者11号探测土星的主要成果: 1.发现了一个新的土星卫星——土卫12 现已定名为1979 S1,该卫星的直径估计为400公里。
NASA launched Pioneer 11 space probe on April 5, 1973 after more than six years of long flight with a total travel volume of 3.2 billion kilometers reaching Saturn on September 1, 1979 (20,800 km from Genting Genting ), When it is about 1.6 billion kilometers away from Earth. Pioneer 11 approached Saturn in the process of continuous Saturn for 10 days shooting and exploration, access to a lot of information. Here is a brief overview of the main achievements of Pioneer 11 in the detection of Saturn: 1. A new Saturn satellite was discovered - Titan 12 has now been named 1979 S1, and the satellite has an estimated diameter of 400 km.
