Take 2021 PH27, for example.
The newly-discovered asteroid is currently zipping along an uneven path, completing one trip around the sun in just 113 days.
“2021 PH27 gets so close to the Sun that its surface temperature gets to around 900 degrees Fahrenheit at closest approach, hot enough to melt lead.”
As for 2021 PH27, researchers say its unstable orbit indicates that it will probably crash into Mercury, Venus, or the Sun within the next few million years.
That’ll hopefully give us enough time to study it.
