55 Cancri location

Further to my previous post earlier, this is a quick follow up to let people know where the star 55 Cancri is located within the constellation of Cancer.

Using the Kstars astronomy package [1].

Illustrates the constellation showing the 5 main principle stars. At the top there is $\iota$ Cancri. Just below this is a red star, this is 55 Cancri which, Wikipedia states, is also known as $\rho$ Cancri [2] and is part of a binary star system.

Cheops telescope operational

Europe's Cheops telescope begins study of far-off worlds.

Interesting article on the BBC News science page on 16/4/2020. Looks like there could be some exciting discoveries made with the Cheops Telescope [1].

Planet formation is an interesting field of astronomy and we are finding new planets, not just different sizes but also composition. Exciting times ahead.

I have opened up a discussion [4] on Science forums [2] on this topic.

If readers are interested in learning more about planetary science please see the link to OpenLearn [3] below.

One of the exoplanets mentioned in the article is 55 Cancri -e[5] which looks pretty interesting, Wikipedia suggests this is '8.63 Earth masses' and therefore the first 'super Earth'.

We can also identify the composition of these planets by using various techniques including looking at the absorbtion spectrum

I also acknowledge here that Wikipedia, is not a suitable academic resource.

You may want to search on the Astrophysical Journal website [7] as there is an article that relates to 55 Cancri e[8].

I am using the Deluge bit torrent client to download and stream various free software ISOs. You may find that using this, causes your connection to slow down and other internet operations are slow too. The solution is to pause the download while you do other tasks.

Right click on the torrent you want to pause, and simply select pause, to resume, select resume.
