QLD Town Named After Comet see it return – 5000 Years Early.

Great Comet of 1844, as observed from Van Diemen’s Land (now known as Tasmania), off Australia. This comet was discovered on 18 December 1844, and was visible with the naked eye until the end of January 1845, during which time it was one of the brightest objects visible in the Southern Hemisphere. Comets are icy bodies from the outer solar system that boil and form a bright tail of gas and dust as they approach the Sun.

The Great Comet on 1844 was seen in many places across the world  but prominently here in Australia. “Ludwig Leichhardt saw Comet Wilmot in the sky on 29 December 1844 while walking along the banks of a creek in central Queensland (Lang, 1847:315), prompting him to name the site Comet Creek. The town of Comet, Queensland (originally Cometville) takes its name from this creek (now called Comet River, Edwards, 1994).” (Hamcher & Norris)

That comet is a long period comet, which means we won’t see it again for a long time. Try 5,500 years.

But a funny thing happened in late 2019 when C/2019 Y4 (ATLAS) was discovered. It’s calculated orbit appears to be the same as Comet Wilmot that Leichhardt saw back in 1844. This suggests both comets may both be fragments of a single, larger comet that broke up some time in the past. The new Comet currently flying towards us for a close approach in late May is already in outburst as it comes for a close swing around the Sun.

Like most comets it’s difficult to predict whether this will become a bright, naked-eye comet like the one that was seen with no equipment from the banks of Comet River so long ago. But astronomers have a good feeling about it and it may peak to about 4-6 before breaking up as it melts around perihelion. With any luck, we’ll get to see a tail!

In any case, if it is the same piece of flying space ice and rock that Comet, QLD is named after, this may be their only chance to see their namesake one more time.

It’s unlikely we’ll get a good view of it from the Southern Hemisphere unless it gets bright enough to see in the twilight at sunrise or sunset as you might be able to tell from this projected path.

Has anyone told the folks down at the local watering hole?

Earth has 2 Moons Now

A new car-sized chunk of space rock has been captured by the Earth’s gravity and is now orbiting the Earth as a “mini-moon”. Designated 2020 CD3 it was discovered by astronomers Theodore Pruyne and Kacper Wierzchoś on 15 February 2020 at Mount Lemmon Observatory during a regular survey of near-earth objects. Its orbit around Earth…

The Fermi Paradox – Where are all the Aliens?

In the 1950s, a group of astrophysicists were walking to lunch discussing the possibility of life elsewhere in the universe apart from Earth. One of those physicists, Enrico Fermi then casually asked “But where is everybody then?” The basic idea is that given the vastness of observable space and time with which life should have…
