The story in 1 scene
An orbit like Earth’s
This small asteroid circles the Sun on a path very similar to Earth’s, so it comes back near us every few decades. Its total chance of impact between 2069 and 2122 is about 1 in 360 — high for this list — but it is small, so it ranks fifth.
Why?It moves at almost the same speed and in almost the same direction as Earth, so when it comes close it drifts past slowly. That makes it easier for Earth’s gravity to grab.
What nextFor the same reason it is easy for spacecraft to reach, and it has been studied as a possible target for a crewed asteroid mission.
