caption_attribution_description: English: 7 minute exposure of comet 94P/Russell 4 with a 24" telescope. Comet 94P was 2.2 AU from the Sun with perihelion (closest approach to the Sun) on March 29, 2010. You can just make out signs of a cometary tail in this image taken at 2010-02-19 11:30 UT.
context_page_description: 94P/Russell 4 is a periodic comet in the Solar System. It fits the definition of an Encke-type comet with. It was discovered by Ken Rusell on photographic plates taken by M. Hawkins on March 7, 1984. In the discovery images, Russell estimated that the comet had an apparent magnitude of 13 and a noticeable tail of 5 arc minutes. In the year of discovery, the comet had come to perihelion in January 1984.
  With an aphelion of 4.7 AU, comet 94P currently has an orbit contained completely inside of the orbit of Jupiter.
  In July 1995, 94P was estimated to have a radius of about 2.6 km with an absolute magnitude of 15.1. It may have a very elongated nucleus with an axial ratio of a/b >= 3.
