Default future feared earth impactor just flew past

Apparently one of the things that makes Apophis easier to predict
is it spins on 2 axes. If it was just the one it would be emitting heat
mostly from one side which would affect its orbit. Spinning in 2 dirs
evens out the heat emissions making the orbit a bit more stable.

Apophis, a Feared Future Earth Impactor, Just Flew Past Us
The Debrief, 8 Mar 2021
In 2004 when Apophis was initially discovered, astronomers were
concerned about its possible trajectory, which appeared to put it on a
collision course with Earth. Fortunately, the more than 300-meter-wide
space rock was detected early enough that we had time to prepa the
possible impact wasn't expected to occur until 2029.
Based on existing data collected by NASA, the threat of a 2029 impact
with Apophis was eventually ruled out. Although its 2029 passage will
be close at just under 20,000 miles from Earth--placing its path
between Earth and the Moon--it is not believed that the asteroid will
represent a threat at that time.
