NASA has issued an alert for a 100-foot asteroid hurtling towards Earth tomorrow. Should you be concerned? Let's dive in and find out

NASA’s Lucy mission will continue its journey to explore the Jupiter Trojan asteroids, which share Jupiter’s orbit around the Sun, in 2025. One key event for Lucy is its flyby of the inner main-belt asteroid 52246 Donaldjohanson, scheduled for April 20, 2025.

Through the International Asteroid Discovery Project, Daksh Malik successfully discovered asteroid 2023 OG40 in the main asteroid belt of the solar system.

For a brief, but exciting, time last year, Earth had two moons. A small asteroid lingered close to our planet in its orbit around the Sun, temporarily caught by Earth’s gravity to become a far away mini-moon. A closer look at the space rock reveals a rather familiar origin: Earth’s mini-moon might actually be a broken-off piece of our regular Moon.

Alinda, measuring 2.6 miles wide, will be visible this weekend. Stargazers can spot it using basic equipment or watch a livestream. Events like this occur once in a decade.

For a few months, Earth had a second moon — a tiny asteroid that may have been a piece of our own Moon

The asteroid is estimated to be between 656 and 1,443 feet across, and will pass at 16 times the distance to the moon.

Further simulations on flybys into the inner Solar System revealed one of our own planets might be flung out of the ballpark within the following 20 million years or so in just 2 percent of cases. In all others, the inner planets remained in slightly altered but still relatively harmonious orbits.

"it's not completely unusual for asteroids to be near the Earth," Gallagher said. "Our moon is about a quarter million miles away from the Earth. So something 7.6 million miles out would be many, many, many times father away from the Earth than the moon is. No cause for alarm."

Typically, asteroids - like the one depicted in this artist's concept - originate from the main asteroid belt between the orbits of Mars

An unusual looking 33-foot-long object discovered orbiting Earth last year may have come from a surprising place.
