Tomorrow night, the planets Venus and Jupiter will be very close to each other in the night sky–3 degrees apart, which is about the width of two fingers held at arm’s length. These two planets are the brightest ones visible to the eye. When planets line up in the sky, it is called a conjuction. Although the planets may look like they are close together, they are really more than 448 million miles apart from each other.
