JUPITER and Saturn are edging closer together in the solar system and are visible tonight. NASA has been sharing some handy tips on how to see the so called 'Christmas Star'.

According to our weather map, it'll be raining at 5 p.m. So I guess yet another no show, just like the eclipse of 1999.

For months, the two largest planets in our solar system, Jupiter and Saturn, have been gradually moving closer and closer to each other in our night sky. And on December 21, they will be at their closest, appearing just a tenth of a degree apart: that’s only about one-fifth the size of the full Moon! In fact, the planets will be so close that they will, from some perspectives, appear to overlap and become one object in the night sky with the naked eye. However, while they may appear close in the sky to us, the planets are actually hundreds of millions of miles apart.

These planets align every 20 years because Jupiter orbits the Sun every 12 years, while Saturn takes 30. So, every couple of decades, Jupiter laps Saturn. However, this year’s conjunction is especially rare. These planets have not been this close and visible in the night sky away from the glare of the Sun since the year 1226, and this won’t happen again until March of 2080.
