'Eta Aquarid Meteor Fall' (Eta Aquariid Meteor Shower), which has been active since April 15, is scheduled to reach its peak on May 5 and 6.
About 'Eta Aquarid' Meteor Fall
- 'Eta Aquarid' meteor shower One of the meteor showers that occurs biennially.
- The Eta Aquariid meteor shower is formed when the Earth Passes through the orbital path of Halley's Comet.
- Completing one orbital revolution of Halley's Comet: Halley's Comet orbits the Sun approximately every 76 years and when the Earth passes through its orbit, 'Eta Aquarid' is formed from Halley's debris.
- Discovery of Halley's Comet: The periodic nature of the appearance of Halley's comet was discovered by astronomer Edmund Halley in the year 1705.
- Last appearance of Halley's Comet: Halley's Comet was last seen in 1986 and is expected to be seen again in the inner Solar System in the year 2061.
- Orionids Meteor Shower: This shower occurs in October and also Halley's Comet Debris Is caused by.
- features
- Lighted path/sign: The 'Eta Aquarid' meteor shower consists of intense meteors that leave behind them Creates a long blazed path/mark.
- Fast Speed/Communication: It is about 66 km in the Earth's atmosphere. Moves at a speed of 2.37 lakh km per second (2.37 lakh km per hour).
- Lighted path/sign: The 'Eta Aquarid' meteor shower consists of intense meteors that leave behind them Creates a long blazed path/mark.
- period and peak period
- Time period in one year: The period of the Eta Aquariid meteor shower usually occurs between April 21 and May 12 each year.
- The number of visible meteors remains low until reaching its peak around May 5 or 6.
- Best visibility location: these showers Southern hemisphere In Indonesia and Australia These are best seen in countries like
- Location of Radiant Showers: southern hemisphere observers Showers of Radiance Due to the location, meteorites are clearly visible in the sky.
- 'Eta Aquarid' 'Radiant Point of Meteors'Located within the constellation 'Aquaris'.
- Due to fog in the morning, observers have difficulty seeing them.
- In the Northern Hemisphere, Eta Aquarid meteors are common. “Earthgrazers” That is, they appear in the form of long meteors, which appear to touch the earth's surface.
- 'Eta Aquarid' 'Radiant Point of Meteors'Located within the constellation 'Aquaris'.
- Location of Radiant Showers: southern hemisphere observers Showers of Radiance Due to the location, meteorites are clearly visible in the sky.
- Time period in one year: The period of the Eta Aquariid meteor shower usually occurs between April 21 and May 12 each year.
What are comets?
- Comets are icy remnants of the time when our solar system was forming about 4.6 billion years ago.
- Mixture: These contain a mixture of dust, rocks and ice.
- Orbital characteristics of comets
- Elliptical Orbit: Comets move around the Sun in highly elliptical orbits.
- Completing one revolution: Some comets may take hundreds of thousands of years to complete one orbit around the Sun.
- size of comet
- Most comets are about 10 kilometers wide.
- As comets get closer to the Sun, they heat up and expel gases and dust particles outward.
- Due to this, their top can be bigger in size than the planets.
- tail formation
- Material ejected from the comet forms the tail, which can extend millions of miles away from the comet.
- These tails are a distinctive feature of comets when they are near the Sun.
- Material ejected from the comet forms the tail, which can extend millions of miles away from the comet.
- Number of known comets
- Current Comet: So far 3,910 comets have been identified by NASA.
- However, scientists believe there are billions of comets orbiting beyond Neptune, in regions such as the Kuiper Belt and the more distant Oort Cloud.
Relationship between meteor showers and comets
- Meteor showers occur when the Earth passes through dusty trails left by comets in space.
- Visible Streaks: Comet debris burns up in Earth's atmosphere, creating visible streaks.
- these visible lines Known as meteor or 'shooting star'.
- A small tail behind a burning shooting star Is also made.
- these visible lines Known as meteor or 'shooting star'.
Characteristics of Meteorites
- Meteors: These are small pieces of dust or rock, which as soon as it hits the Earth's atmosphere Get burnt.
- Most meteors are actually as small as grains of sand and disappear in the sky.
- Meteorite: Sometimes large meteors remain safe and hit the ground and then Is called meteorite.
meteorite formation
- Meteor showers are formed when Earth passes through the comet's orbital plane and encounters debris left behind by the comet.
- As Earth passes through this debris field, the sky lights up with small and large meteoroids.
