In the past month, Earth experienced some of its shortest days on record. The planet spun quickly enough to shave 1.4 milliseconds off of its usual 24-hour day. These natural accelerations in Earth’s ...

How can scientists use spin as a fossil record for planetary evolution? This is what a recent study accepted for publication in The Astronomical Journal hopes to address as a team of scientists ...

For some time, astronomers have theorized that there is a connection between planetary mass and rotation. In the solar system, Jupiter and Saturn both rotate rapidly, completing a rotation in roughly ...
