Comets Sighted Till Now Who Discovered The Comet : Comets have been discovered by many different astronomers over the centuries. Some of the most notable comet discoverers include:Edmond Halley: Discovered the periodic comet now known as Halley's Comet in 1682.Caroline Herschel: Discovered several comets in the late 18th and early 19th centuries, including Comet 35P/Herschel-Rigollet in 1788.Charles Messier: Compiled a list of non-cometary objects, but also discovered several comets, including the Great Comet of 1769.William Herschel: Discovered several comets in the late 18th and early 19th centuries, including Comet C/1786 P1 (Herschel).Giovanni Schiaparelli: Discovered several comets in the late 19th century, including Comet 1866 I.Carolyn Shoemaker: Discovered or co-discovered more than 30 comets during her career as an astronomer in the 20th century.What is Comet : A comet is a small celestial object that is made up of ice, dust, and rocky debris. Comets are often called "dirty snowballs" because they are made up of ice and dust that have been frozen together since the formation of our solar system.Credit: NASA/JPL-CaltechComets typically have highly elliptical orbits that take them from the far reaches of our solar system to close to the Sun. As a comet approaches the Sun, the heat causes the ice in the comet to melt, releasing gas and dust that form a glowing coma (a bright, fuzzy cloud) around the nucleus of the comet. The gas and dust can also form a long, glowing tail that can stretch millions of kilometers behind the comet.Comets are believed to be remnants of the early solar system and studying them can provide insights into how our solar system formed and evolved over time. They have fascinated people throughout history and have been viewed as omens of good or bad luck, depending on the culture and time period.Comet Comes From : Credit: NASA/JPL-CaltechComets are believed to originate from two main sources in our solar system: the Kuiper Belt and the Oort Cloud.The Kuiper Belt is a region of our solar system beyond the orbit of Neptune that contains many small icy bodies, including Pluto. Some of these icy bodies can be dislodged from the Kuiper Belt and sent into the inner solar system, where they become comets.The Oort Cloud, on the other hand, is a vast spherical region that surrounds the outermost reaches of our solar system. It is believed to contain billions of icy objects, including comets. When a passing star or some other gravitational disturbance causes one of these objects to be dislodged from the Oort Cloud, it can be sent on a trajectory towards the inner solar system, where it becomes a comet.Comets from the Kuiper Belt tend to have shorter orbital periods and are generally more stable, while comets from the Oort Cloud can have very long orbital periods and are often more unpredictable in their behavior.-: Comet Sightings Till 2026 (Sept'26) :-1.Great Comet of 1807 (C/1807 R1): This was a very bright comet that was visible to the naked eye for several months.
