Skewed planetary pathways around a star aren't so strange after all.
Scientists have known that all the planets in our solar system follow a slightly slanted trajectory as they circle the sun — but a new study shows that the phenomenon may not be unique to our cosmic neighborhood. It's common, the authors say, for distant exoplanets to exhibit orbital tilts as well. The discovery suggests it doesn't take much to make a planet's orbit tilt, although exactly how it happens requires some investigation.
