Space rocks: the difference between asteroids, comets, and meteors
Some objects in our solar system don't orbit the Sun as neatly as planets do. Instead, rocky objects of different sizes and shapes float around our solar system, and sometimes, get really close to Earth and even enter our atmosphere.
Asteroids are essentially rocks that orbit the Sun. Most are small, but some can be pretty big — like Vesta , which measures 525 kilometers across, or Ceres the largest asteroid in our solar system, with a whopping 946-kilometer diameter.

Before the solar system had planets, the sun had rings -- bands of dust and gas similar to Saturn's rings -- that likely played a role in Earth's formation, according to a new study.
Has the impact flux of small and large asteroids varied through time on Mars, the Earth and the
The impact flux over the last 3 Ga in the inner Solar System is commonly assumed to be constant through time. However, asteroid break-up events in the main belt may have been responsible for cratering spikes over the last ~2 Ga on the Earth-Moon system.
It's Time to Focus on What was Good in 2021
Quite a few asteroids came within 0.07 lunar distances of the Earth last year. In April, an SUV-sized asteroid, traveling at 18,700 mph came within 12,000 miles of our atmosphere.
After previous administrations' talk and negligible action, the Biden administration passed a $1.2 trillion bipartisan infrastructure package. The environmentally/socially necessary Build Back Better Act should hopefully follow.
