Spartan Posted November 13, 2020 Report Posted November 13, 2020 @kittaya This week, there will be some not so familiar sights in the sky: all seven of the planets that make up our solar system will be visible at various points throughout the day. Venus and Mercury are bright enough to see in the mornings, while Mars, Jupiter and Saturn will be easier to see at night. Earth Sky published a guide to viewing all of these planets, along with Uranus, on its website. Joe Guzman, an astronomer and educator at After School Matters in Chicago, has already told his students about this week's celestial phenomenon. "Early this morning, I took the time to get a look at the crescent moon," Guzman told CNN. "And when the sun sets tonight, you'll definitely be able to see Jupiter and Saturn." Why is this happening? The visibility of the planets is just a cosmic coincidence. "It's the dance of the planets around the sun," Guzman said. "It's a natural phenomenon, and it happens once in a while. it's not rare, but it is infrequent. It just kinda happens that they'll still on this side of the sun, but they'll start to separate again soon." In the meanwhile, Guzman thinks everyone should get their hands on a telescope. Sky & Telescope reported that the sale of telescopes has already been rising since the pandemic began, with companies seeing "an increase in business from 60% to 400% over the previous year." Guzman recommends that novice sky watchers be on the lookout for Saturn, his personal favorite. "You can catch its rings quite easily," Guzman said. "It's definitely worth a watch." 1 Quote
KhalilGibran Posted November 13, 2020 Report Posted November 13, 2020 I have a big doubt. We all know planets travel through constellations earth is in which constelletion i.e rashi. Quote

From our nearest neighbouring star (not counting the Sun) we would be in Cassiopeia. Explanation: Constellations are relative to the observer. From the Alpha Centauri system (3 stars including Proxima Centauri a.k.a. Alpha Centauri C) our sun would appear as an extra star in the constellation of Cassiopeia. From Barnard's star our sun would appear as a bright extra star in the constellation of Monoceros. PS: Source Google. Quote

So Earth doesnt fall into any of them. the above answer was assuming if you are on another planet or star..which is not relative to our constellation system, Quote
Spartan Posted November 13, 2020 Author Report Posted November 13, 2020 On a clear night, we might be able to see about 9,000 stars in the sky, (estimates vary) some bright, some not so bright, some very dim and so on. People thousands of years ago ‘grouped’ stars of roughly the same brightness in different areas of the sky and imagined that each took up the shape of something familiar – an animal, a thing, and named it accordingly. Thus, over a long period, the entire night sky was made up 88 such ‘constellations’ also known as ‘asterisms’. This made it easy for them to refer to a particular star, quoting the constellation. Therefore, as constellations are groups of stars in the sky, Earth does not belong to any constellation. Quote
