The return of Halleys comet!

What are you most excited about for the future?

See Wikipedia for information https://en.m.wikipedia.org/wiki/Halley%27s_Comet.

I don’t know all the information about Halleys comet but I did see it in 1986 although it wasn’t as spectacular as expected. But I watched a TV programme that showed photos of it from a probe called Giotto that had been sent out to investigate the comet. The debris and ejecta from the out gassing of the comet meant that the view stopped before the comet nucleus was fully visible. The idea that a comet is a dirty snowball was suggested around then?

Halleys comet returns every 76 years. It is next due in our skies in 2061. I might just get to see it! That is because it is a short period comet as opposed to ones that have much longer orbits only entering the centre of the solar system again after hundreds or thousands of years.

The comet was named after Sir Edmond Halley who in 1705 worked out its orbit around the sun and calculated when it would return. I believe he was made astronomer royal because of it but I might be wrong!

One thing to also note is that a meteor shower happens each year, I think in March? This is caused by dust and debris blown off Halleys comet by the solar wind. The material is left behind and the Earth passes through this debris over a couple of days each year. The resulting meteor shower or shooting stars are basically tiny pieces of cometary dust and small specks of material burning up in the earth’s atmosphere as they enter it.

I’m interested in astronomy but I’m no expert, but Halleys comet has always excited me.
