To change an asteroid's direction, scientist's are considering the use of space craft thrusters as gravity tractors that slowly pull it away from Earth. 🧭

A very tiny gravitational change early on can mean the difference between an impact and a near miss.

NASA's Double Asteroid Redirection Test, or DART, is a defense-driven initiative that uses space crafts to change the motion of an asteroid in space using a kinetic impactor technique. 📡

This technology could be detrimental to the safety of our planet.

Potentially hazardous asteroids are at least 500 feet in diameter and orbit within 4.5 million miles of Earth. 

Apophis, one of the most popular asteroids in sight, will be within 20,000 miles of our planet on Friday, April 13th, 2029. 😨💫

The main asteroid belt is filled with rocks ranging from a few meters wide to hundreds of kilometers in diameter. 🪨

Like our planets, asteroids orbit the sun, taking between three and six years to complete their journey. ⏳

When a meteor hits the ground, it vaporizes, releasing incredible amounts of kinetic energy. 💥

The impact of an asteroid on Earth would create waves of effects, from earthquakes to fires and unimaginable changes in climate, health, and agriculture. 🌎

Around 66 million years ago, a rock twice the size of Mount Everest came crashing down at about ten miles per second, almost 50 times faster than a speeding bullet. 🛰️☄️

Within hours, most of the dinosaurs within North and Central America were wiped out.

Predicting the likelihood of an asteroid colliding with Earth is like playing a round of roulette: even the best in the game have to risk it all.

The Portuguese man o' war (Physalia physalis) is not a true jellyfish but a siphonophore. So while it may appear to be an individual organism, it’s actually a colonial hydrozoan.
