Halley's Comet
Halley's Comet is due to return and be visible from Earth in 2061. What I would like to know is will this be visible from the northern as well as the southern hemisphere also what month and (preferably) day of the month will it be visible and thirdly will there be any other celestial events at the same time such as meteor shower, or is it too early to know?

 * As a general comment, a comet doesn't just zip into and out of view on a particular date. A bright comet may be visible every night for weeks or more, during which its position against the background of stars will vary gradually but noticeably.  Typically, during that time at first it is just barely visible, then it gets brighter from one night to the next, then eventually it gets fainter again.  It's not too early to predict where the comet will be on any particular date, but knowing for how long it will be bright enough to see is another matter. --174.95.161.129 (talk) 20:58, 10 November 2020 (UTC)·
 * I need latitude for max detail. Both hemispheres can see but some latitudes much different than others. Sagittarian Milky Way (talk) 22:06, 10 November 2020 (UTC)
 * Note also that the brightnesses of comets are notoriously hard to predict, even much closer to their inner-Solar system passages, let alone decades in advance. See here, for example, for details of why. {The poster formerly known as 87.81.230.195} 90.200.136.194 (talk) 00:54, 11 November 2020 (UTC)
