Oldest Planets Found.

Data from the venerable Kepler mission has uncovered the oldest know planets that we have found to date.

Kepler-444 is 11.2 billion years old and has five Earth-sized planets in orbit.

The five planets are a little smaller than Earth.

Additionally, they are way too close to their sun (about 1/10 the distance, or about 9 million miles, of the Earth-Sun orbit).  This makes it unlikely that they could hold life as we know it.  But, we don’t have a very good definition of what life is.

But the star and its planets is fairly amazing due to the age.  Only 117 light years from Earth, Kepler-444 is five times older than our solar system, so it formed very shortly after the big bang.  The age is measured using a technique called asteroseismology, which measures the oscillations of a star caused by sound waves trapped within it.  These sound waves cause small pulses in the star’s brightness, which are analyzed to measure its diameter, mass and age.
