Is the source of Aquarids and Orionids meteor showers?

The pieces of space debris that interact with our atmosphere to create the Orionids originate from comet 1P/Halley. The dust grains eventually become the Orionids in October and the Eta Aquarids in May if they collide with Earth's atmosphere. Comet Halley takes about 76 years to orbit the sun once.

And another question, why are they called leonid shower?

The Leonid meteor shower gets its name from the constellation Leo, the lion, where its meteors appear to originate. If you directly face Leo, you may miss the meteors with longer tails. What are Eta Aquarids and Orionids called? The Eta Aquarids are one of two annual showers caused by pieces of Halley's Comet. The other one is the Orionids, which flies by in October. The Eta Aquarids are named after their apparent "radiant" point in the constellation Aquarius, near one of its brightest stars, Eta Aquarii.

What are the Leonid meteors?

The Leonids (/?li??n?dz/ LEE-?-nidz) are a prolific meteor shower associated with the comet Tempel?Tuttle, which are also known for their spectacular meteor storms that occur about every 33 years. Earth moves through the meteoroid stream of particles left from the passages of a comet. Where can I find South Taurid meteors? Both the Northern and Southern Taurids will appear to radiate from the constellation Taurus, which is found to the northwest of the constellation Orion. The Taurids will mostly appear in the area around Taurus, so find the celestial bull to center your viewing and then scan the skies and constellations around it.

And another question, how old is the taurid meteor stream?

Taurids facts Encke and the Taurids are believed to be remnants of a much larger comet, which has disintegrated over the past 20,000 to 30,000 years. The Taurids are a relatively slow shower, moving across the sky at about 17 miles per second or 65,000 miles per hour.
