Beyond Jupiter, The World of Distant Minor Planets: (90377) Sedna

JOA 2020, Vol. 10, No. 3, Page 22

Author(s): Konrad Guhl

Abstract: Since 2016, JOA regularly publishes portraits of objects beyond Jupiter's orbit. This short communication on the TNO Sedna tells the story of discovery, the orbit and the meaning behind its name. Size and physical properties follow data published up to 2020. A light curve from an occultation is presented and an outlook for coming stellar occultations is given.
