Articles and discussion about Asteroids.
Asteroids are small rocky, metallic, or icy bodies that orbit around the Solar System. Larger asteroids have also been called planetoids, and those with a tail are referred to as comets.
Asteroids have collided with the major planets before in the past, releasing huge quantities of energy, leaving craters and devastation in their wake. However, most asteroids orbit far from any planet on relatively stable orbits. Asteroid mining has been proposed as a future industry - if successful, a huge wealth of minerals and resources could be within our grasp.

Asteroid 1006 pm EST N MA
Just saw a huge 4s green fireball with chunks flying off it in Northern MA. If you are missing a satellite, I can let you know the road I was on to help pinpoint if it didn't hit a house.

My niece was telling me about the Nadie crater and then I had a question
With the sheer size of the asteroid and the possible damages from the impact, could that possibly be the reason behind the eye of the Sahara(Richat Structure)? And if so, would that have been enough to erase whatever civilization(s) in the area of the time?? Sorry if this isn’t the right place to ask this, but I’m kinda curious about this new discovery!(new to me)

Question about K-Pg Boundary
Hello! Can anyone help me to understand the source of the high amounts of iridium in the K-Pg Boundary? Is the iridium found in the boundary actually a part of the asteroid itself that caused the mass extinction at the end of the Cretaceous? Thank you!
