Cometary proof of a planet past Pluto —, Could 6, 1972
There have been solutions that our photo voltaic system may need a tenth planet…. Within the April Publications of the Astronomical Society of the Pacific, a mathematician … presents what he says is “some very fascinating proof of a planet past Pluto.” The proof comes from calculations of the orbit of Halley’s comet.
The 1972 proof by no means yielded a planet, however astronomers haven’t stopped wanting — although it turned a seek for Planet 9. Within the mid-2010s, scientists hypothesized that the tug of a giant planet might clarify the within the photo voltaic system’s debris-filled Kuiper Belt (SN: 7/23/16, p. 7). However that proof (SN: 3/13/21, p. 9). Researchers utilizing the Atacama Cosmology Telescope in Chile to scan practically 90 p.c of the Southern Hemisphere’s sky , the staff reported in December 2021.
