Asteroid Close Calls: Earth's Encounter and Impact Risks
In the next few years, Earth will have some close calls with asteroids, giant space rocks.
One, named Apophis, will pass very close, and another might hit the Moon, possibly sending space debris our way.
Scientists are watching these rocks closely because, even though big asteroid hits are rare, smaller ones can still cause big trouble, like the one that exploded over Russia.
Luckily, people are working on ways to protect us, like missions to study and even push asteroids away if they get too close.
Two asteroids, Apophis and YR4 2024, will have close encounters with Earth within the next seven years.
Asteroid YR4 2024 is predicted to hit the Moon in 2032, potentially sending meteorites towards Earth.
A dinosaur-killing asteroid impact happens approximately every 10 to 100 million years.
Smaller asteroids, like the one in Chelyabinsk, Russia, can cause significant damage upon impact.
Space agencies are actively monitoring asteroids and developing strategies to mitigate potential threats.
