He had an interest in astronomy, and worked as a calculator at the university observatory. After graduating he continued on as a junior astronomer. In 1915, the University of Warsaw was evacuated to [Rostov-on-Don](/source/Rostov-on-Don) after the German army invaded Poland, and Subbotin completed his [master's degree](/source/master's_degree) there in 1917. During this time he also published two papers, “On the determination of singular points of analytic functions” and another on singular points of certain [differential equation](/source/differential_equation)s. He then moved to the [Donskoy Polytechnic Institute](/source/w%3Aru%3A%D0%AE%D0%B6%D0%BD%D0%BE-%D0%A0%D0%BE%D1%81%D1%81%D0%B8%D0%B9%D1%81%D0%BA%D0%B8%D0%B9_%D0%B3%D0%BE%D1%81%D1%83%D0%B4%D0%B0%D1%80%D1%81%D1%82%D0%B2%D0%B5%D0%BD%D0%BD%D1%8B%D0%B9_%D0%BF%D0%BE%D0%BB%D0%B8%D1%82%D0%B5%D1%85%D0%BD%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8%D0%B9_%D1%83%D0%BD%D0%B8%D0%B2%D0%B5%D1%80%D1%81%D0%B8%D1%82%D0%B5%D1%82) ([Novocherkassk](/source/Novocherkassk)) where he was appointed a professor of mathematics. In 1922, he accepted an offer to work at the [Central Astronomical Observatory of the Russian Academy of Sciences](/source/Pulkovo_Observatory) as Director in [Tashkent](/source/Tashkent). Preceding and during World War II, Subbotin worked at various astronomical institutions in [Leningrad (Saint Petersburg)](/source/Saint_Petersburg). Subbotin almost starved to death during the [Siege of Leningrad](/source/Siege_of_Leningrad), and was evacuated in February 1942 to [Sverdlovsk](/source/Yekaterinburg) to recover. Near the end of 1942 Subbotin became the Director of the Leningrad Astronomical Institute, and relocated to [Saratov](/source/Saratov) before it was brought back to Leningrad after the German withdrawal.{{cite book |last1=Poggendorff |title=Biographisch-literarisches Handwörterbuch der exakten Naturwissenschaften |url=https://archive.org/details/bub_gb_X7LgAAAAMAAJ |location=Berlin}} On 6 June 1945 Subbotin received the [Order of the Red Banner of Labor](/source/Order_of_the_Red_Banner_of_Labor). In 1963 he was awarded the [Order of Lenin](/source/Order_of_Lenin). Subbotin died on 26 December 1966 in then Leningrad, USSR (now [Saint Petersburg, Russia](/source/Saint_Petersburg)). A memorial plaque was installed at his house at Moskovsky Prospect 206 in 1971 (architect V. V. Isaeva){{Cite web|url=http://www.encspb.ru|title=Энциклопедия Санкт-Петербурга, мемориальная доска М.

He worked on the creation of a catalog of faint stars. After his studies moved to astronomy, he concentrated on [celestial mechanics](/source/celestial_mechanics) to devise new methods to calculate orbits from three observations based on solving the [Euler–Lambert equations](/source/Euler%E2%80%93Lambert_equations).{{cite journal|first=G.

“... Subbotin not only showed the possibility of improving the convergence of the trigonometric series by which the behaviour of perturbing forces is represented, but also gave an expression for determining [Laplace](/source/Laplace) coefficients and presented formulas for computing the coefficients of the necessary members of the trigonometric series.”{{Cite book|chapter-url=https://www.encyclopedia.com/science/dictionaries-thesauruses-pictures-and-press-releases/subbotin-mikhail-fedorovich|title=Complete dictionary of scientific biography|last=Kulikovsky|first=P.

Subbotin wrote a three-volume work called “Course in Celestial Mechanics" (1933–49), in which for the first time in Russian the main questions of celestial mechanics were described in detail. He was the author of a number of fundamental studies on the history of astronomy. He was the editor-in-chief of the Astronomical Yearbook of the USSR, published by the Institute of Theoretical Astronomy of the [Academy of Sciences of the USSR](/source/Russian_Academy_of_Sciences). ==Celestial objects named after Subbotin== *[1692 Subbotina](/source/1692_Subbotina), is a carbonaceous asteroid from the middle region of the asteroid belt, approximately 37 kilometers in diameter. *''[Subbotin](/source/Subbotin_(crater))'' is a 67 km-wide lunar crater on the far side of the Moon.{{cite journal |date = October 1967 |title = Mikhail Fedorovich Subbotin (1893–1966) – Obituary |url = http://adsabs.harvard.edu/cgi-bin/bib_query?bibcode=1967SvA....11..375. |journal = Soviet Astronomy |volume = 11 |pages = 375–376 |bibcode = 1967SvA....11..375.}} {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = http://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |access-date = 2019-01-06 |archive-url = https://wayback.archive-it.org/all/20170701101601/http://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |archive-date = 2017-07-01 |url-status = live }} thumb|Subbotin Moon crater ==References== {{Reflist}} {{authority control}} {{DEFAULTSORT:Subbotin, Mikhail}} Category:Soviet astronomers Category:Soviet mathematicians Category:People from Płock Governorate Category:1893 births Category:1966 deaths --- Adapted from the Wikipedia article [Mikhail Subbotin](https://en.wikipedia.org/wiki/Mikhail_Subbotin) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Mikhail_Subbotin?action=history)).
