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.
Answer Wiki. As of 2015 August 05, Comet 1P (Halley) is 34 astronomical units (AU) from the Sun -- a bit over 5 billion km out. As seen from the Earth, it would be in the constellation of Hydra. Comet Halley is still moving outward in its orbit, and will not reach its aphelion (farthest point from the Sun) until 2025.
