Having made its closest approach to the sun at the end of last month, it is expected to do the same to Earth around 13 October.<\/p>\n<figure id=\"f0c50733-ae91-47ea-9cff-5090d790a74c\" data-spacefinder-role=\"richLink\" data-spacefinder-type=\"model.dotcomrendering.pageElements.RichLinkBlockElement\" class=\" dcr-1your1i\"><gu-island name=\"RichLinkComponent\" priority=\"feature\" deferuntil=\"idle\" props=\"{&quot;richLinkIndex&quot;:5,&quot;element&quot;:{&quot;_type&quot;:&quot;model.dotcomrendering.pageElements.RichLinkBlockElement&quot;,&quot;prefix&quot;:&quot;Related: &quot;,&quot;text&quot;:&quot;Starwatch: Pisces emerges in the eastern sky as the nights lengthen&quot;,&quot;elementId&quot;:&quot;f0c50733-ae91-47ea-9cff-5090d790a74c&quot;,&quot;role&quot;:&quot;richLink&quot;,&quot;url&quot;:&quot;https:\/\/www.theguardian.com\/science\/2024\/sep\/30\/starwatch-pisces-emerges-in-the-eastern-sky-as-the-nights-lengthen&quot;},&quot;ajaxUrl&quot;:&quot;https:\/\/api.nextgen.guardianapps.co.uk&quot;,&quot;format&quot;:{&quot;display&quot;:0,&quot;theme&quot;:0,&quot;design&quot;:0}}\"\/><\/figure>\n<p class=\"dcr-1eu361v\">\u201cThe thing about comets is that the closer that they are to us, to the Earth, the brighter they are, but also the closer they are to the sun, the brighter they are. So the closest approach isn\u2019t necessarily going to be the brightest time,\u201d said Brown, noting that may instead fall around 9 October.<\/p>\n<p class=\"dcr-1eu361v\">At that point, however, the comet will be almost directly between the Earth and the sun. As a result, said Brown, the best time to look for it will be a few days before and after.<\/p>\n<p class=\"dcr-1eu361v\">\u201cNaked-eye-visible comets are rare enough as it is, and this one has the potential to be amongst the brightest that we\u2019ve seen in the last few decades. So it\u2019s certainly worth a go,\u201d he said.<\/p>\n<p class=\"dcr-1eu361v\">Brown said it was difficult to be sure how bright the comet would become as it approached.<\/p>\n<p class=\"dcr-1eu361v\">\u201cBy the looks of it, it is already visible to the unaided eye in good conditions, and there is a chance that it will get considerably brighter,\u201d he said. \u201cBut how bright? We honestly don\u2019t know.\u201d<\/p>\n<p class=\"dcr-1eu361v\">Brown said stargazers in the northern and southern hemispheres had a chance of glimpsing the comet.<\/p>\n<p class=\"dcr-1eu361v\">At present, he added, viewers should look east in the early morning before sunrise, towards the constellation of Sextans.<\/p>\n<figure data-spacefinder-role=\"inline\" data-spacefinder-type=\"model.dotcomrendering.pageElements.NewsletterSignupBlockElement\" class=\" dcr-173mewl\"><a data-ignore=\"global-link-styling\" href=\"#EmailSignup-skip-link-13\" class=\"dcr-jzxpee\">skip past newsletter promotion<\/a><\/p>\n<aside aria-label=\"newsletter promotion\" class=\"dcr-av5vqf\">\n<p class=\"dcr-1xjndtj\">Our morning email breaks down the key stories of the day, telling you what\u2019s happening and why it matters<\/p>\n<p><gu-island name=\"SecureSignup\" priority=\"feature\" deferuntil=\"visible\" props=\"{&quot;newsletterId&quot;:&quot;morning-briefing&quot;,&quot;successDescription&quot;:&quot;Our morning email breaks down the key stories of the day, telling you what\u2019s happening and why it matters&quot;}\"\/><span class=\"dcr-1eusqlu\"><strong>Privacy Notice: <\/strong>Newsletters may contain info about charities, online ads, and content funded by outside parties.
