Is comet coming back?
Comet Leonard, officially named the C/2021 A1, has approached the Earth after 35,000 years. Astronomers say that this time after crossing the Sun, it will be propelled out of the solar system. As a result, it will never return to the solar system again, so no one after us will have the privilege to see it ever.

What happened to the tail of Comet Encke?
Encke’s Comet loses its tail On 20 April 2007, STEREO-A observed the tail of Comet Encke to be temporarily torn off by magnetic field disturbances caused by a coronal mass ejection (a blast of solar particles from the Sun). The tail grew back due to the continuous shedding of dust and gas by the comet.
What is the albedo of Encke’s comet?
Like most comets, it has a very low albedo, reflecting only 4.6% of the light its nucleus receives, although comets generate a large coma and tail that can make them much more visible during their perihelion (closest approach to the Sun). The diameter of the nucleus of Encke’s Comet is 4.8 km.
