Asteroid China Light 2051 Star - Zhang Yuzhe Star

4. Asteroid Chinese Light 2051 Star - In August 1978, the International Minor Planet Bulletin No. 4420 published by the International Minor Planet Center announced that the asteroid discovered by the U.S. Astronomical Observatory, officially numbered 2051, was named "Zhang Yuzhe Star".

Zhang Yuzhe (1902-1986 AD), a native of Minhou, Fujian, was a famous astronomer and the founder of modern Chinese astronomy. At the age of 17, he was admitted to Tsinghua Xuetang. At the age of 21, he was admitted to the Architecture Department of Cornell University, and two years later transferred to the University of Chicago, where he graduated at the age of 24 and worked at the Yekaiz Observatory after graduating from the astronomy department of the university, and received his doctorate at the age of 27. In 1929, he returned to China as a professor at the Department of Physics of Chuo University and a special researcher of the Institute of Astronomy of the Academia Sinica, and was later promoted to the director of the institute. From 1946 to 1948, he went to the United States again to engage in the study of the spectroscopy of the eclipse binary star. From 1950 to 1984, he was the director of the Purple Mountain Observatory of the Chinese Academy of Sciences. He was the chairman of the Chinese Astronomical Society. After 1950, under his leadership, the planetary room of the Purple Mountain Observatory has been engaged in the discovery and research of asteroids for a long time, discovering hundreds of asteroids and using photometric methods to determine the photoperiopermuth of asteroids. In China, it is the first to apply the basic theory of celestial mechanics to study the orbit of artificial satellites. He has published nearly 100 papers and reports, and published a number of astronomical popular science works.

In 1928, Zhang Yuzhe discovered asteroid 1125 with the 60 cm reflecting telescope of the Yekes Observatory in the United States, and his discovery was internationally recognized, and the discoverer had the right to name the planet. Although Zhang Yuzhe is in other countries, he has a heart for the motherland. Zhang Yuzhe named this planet Zhonghua, which deeply expressed Zhang Yuzhe's love for the mother of the motherland, and since then, there is finally a planet named after China in the history of astronomy.

As an outstanding and advanced representative of modern astronomy in China, Zhang Yuzhe devoted all his life's energy to astronomical research. He personally led the observation and research of planets, asteroids, comets and so on in china. He is a selfless dedication, a scientist who loves the motherland and has made great contributions to the cause of Chinese astronomy. In order to commemorate him, the international astronomical community named asteroid 2051 discovered by the Harvard University Observatory on October 23, 1976 as "Zhang Yuzhe Star".

There is a Chinese star in the sky

Illuminate the deep space and shine light

Hongmeng created a dream far away

The River Han Yi Elephant sent affection
