Jupiter and Saturn will appear to be within inches of each other via a telescope, forming an image like a single star. That celestial happening has been referred to as the Christmas star because of its occurrence near the holiday. Though they’ll seem to be strikingly close to each other, the two planets will still be hundreds of millions of miles apart. When two celestial objects closely approach each other in the sky, astronomers call it a conjunction, according to AccuWeather.
Weather permitting, the best viewing conditions will be near the equator. Hartigan said the planetary duo will appear low in the western sky for about an hour after sunset each evening.
