Halley's comet returns in bits and pieces. Shooting stars should be visible October 21st & 22nd. October 20, 1998: The last time Halley's comet visited Earth, in 1986, many observers were disappointed because the famous comet was barely visible to the naked eye.
The next predicted perihelion of Halley's Comet is 28 July 2061, when it is expected to be better positioned for observation than during the 1985â1986 apparition, as it will be on the same side of the Sun as Earth.
