184 1 In July, 2008, Adams, a 22-year-old college student from Cambridge University, bravely undertook this arduous task after reading the report of the director of Greenwich Observatory. He began to think and calculate the orbit and distance of the extraterrestrial planet Neptune. 1843 At the age of 24, he worked out the preliminary results of this unknown planet. By 1845, 26-year-old Adams had calculated the orbit, mass and position of the imaginary planet. 101October 2 1 day, he sent the calculation results to Airy, the director of Greenwich Observatory in Britain, and asked him to observe the planet with the observatory's large telescope. Unexpectedly, the director did not take the calculation results of young astronomers seriously, and put Adams' calculation results on the shelf without thinking. In June 1846, when he received a copy of the paper published by Le Ye Wei, he found that Le Ye Wei's result was almost the same as that of Adams. He immediately asked Charles, an astronomer at Cambridge Observatory, to search the planet with a telescope, but the astronomer was still skeptical about Adams' calculation results, which made the achievements of the astronomer's years of struggle go to waste.
