Kepler discovers wobbly planet

Kepler discovers wobbly planetWashington, Feb 5 : NASA's planet-hunting Kepler space telescope has found a wobbly planet that spins on its axis much like a child's top.

The planet, designated Kepler-413b, precesses, or wobbles, wildly on its spin axis.

The tilt of the planet's spin axis can vary by as much as 30 degrees over 11 years, leading to rapid and erratic changes in seasons.

In contrast, Earth's rotational precession is 23.5 degrees over 26,000 years.

Researchers are amazed that this far-off planet is precessing on a human timescale.
