Today’s Astronomical Events – April 18th, 2015

2015-04-18

Venus reaches perihelion, its closest point from the Sun, when it will be approximately 107 million kilometers from our parent star. In comparison, the Earth orbits at a distance of about 150 million kilometers (also known as one astronomical unit, or AU.)

Venus can still be seen in the west as a brilliant star-like object for a few hours after sunset.
