Asteroid 1998 KY26's Unexplained Acceleration
Tap title to read story
Near‑Earth asteroid 1998 KY26 shows nongravitational acceleration that gravity alone cannot explain.
The roughly 36‑foot‑wide object is believed to be a near‑Earth asteroid, but something other than gravity appears to be affecting its path.
Scientists refer to KY26's unusual movement as “nongravitational acceleration,” meaning something besides the pull of the sun and planets is affecting its path.
One theory has been that KY26 is a “dark comet” containing buried water that turns to gas and gives the object a push through space, even though astronomers have not detected the cloud or tail normally associated with a comet.
A new peer‑reviewed study by Georgia Institute of Technology researchers Korbin Hansen and Masatoshi Hirabayashi casts doubt on that explanation.
