The Lyrid Meteor Shower Is Back — Here's What You Need to Know

But every April, some of its debris puts on a nighttime light show enjoyed by millions of stargazers: the Lyrid Meteor Shower.

Made of ice, dust, rock and frozen gases, comets are celestial bodies that revolve around our sun and other stars in the universe.

Then over the next few months, it approached our sun before exiting the inner solar system, the area that encompasses every planet from Mercury to Mars — plus the asteroid belt .

Like our beloved planet, it orbits the sun, but we now know that it takes Comet Thatcher approximately 415.5 Earth years to complete one rotation around the life-giving ball of plasma.

However, even after it vanishes, a stream of dust will linger in its place, filling up the orbital route that the icy object used to take around the sun.

To try and predict the intensity of a coming shower, astronomers make computer models that take things like comet trajectories and atmospheric changes into account.
