Comet 46P/Wirtanen next perihelion 2024-May-19

Comet 46P/Wirtanen is a n icy   small Solar System body  that, when passing close to the  Sun , will warm and begin to release gases, a process called  outgassing . This produces a visible atmosphere or  coma , and also a  tail . These phenomena are due to the effects of  solar radiation  and the  solar wind  acting upon the nucleus of the comet. However, this time around, the ion tail will be pointing  away from the Earth and difficult to see due to the geometry. It will hopefully improve as the comet approaches perihelion (19 May 2024). The Comet 46P/Wirtanen nucleus is approximately 1.2  kilometers diameter (example distance & size shown above) and is composed of loose collections of ice, dust, and small rocky particles. Although actual sizes are yet to be determined, the coma may be up to 15 times the Earth's diameter, while the tail may stretch one  astronomical unit . Expected to be sufficiently bright, Comet 46P Wirtanen  may be seen from the Earth without the

Know the astronomical phenomena that we can enjoy in 2018

Comet 46P / Wirtanen, discovered in 1948 by the American astronomer Carl Alvar Wirtanen, takes 5.4 years to travel its orbit around the Sun. On December 12 it will make its closest approach to the Sun and four or five days later it will make its closest approach to our planet and it will appear between the Pleiades and the Hyades.  It will approach about 30 lunar distances and could be observed with the naked eye.  http://www.rguama.icrt.cu/conoce-los-fenomenos-astronomicos-que-podremos-disfrutar-en-el-2018/

Ephemeris

Ephemeris From Wikipedia, the free encyclopedia In  astronomy  and  celestial navigation , an  ephemeris  (plural:  ephemerides ; from  Latin   ephemeris , meaning 'diary', from  Greek  εφημερίς  (ephemeris) , meaning 'diary, journal'  [1] [2] [3] [4] ) gives the positions of naturally occurring  astronomical objects  as well as  artificial satellites  in the  sky  at a given  time  or times. Historically, positions were given as printed  tables  of  values , given at regular intervals of date and time. Modern ephemerides are often computed electronically from mathematical models of the motion of astronomical objects and the Earth. Even though the calculation of these tables was one of the  first applications of mechanical computers , printed ephemerides are still produced, as they are useful when computational devices are not available. The astronomical position calculated from an ephemeris is given in the  spherical polar coordinate system  of  right ascensi
