Venus will be well placed for observation in the evening sky, shining brightly at mag -4.4.
Venus's orbit lies closer to the Sun than the Earth's, meaning that it always appears close to the Sun and is very difficult to observe most of the time. It is observable only for a few weeks each time it reaches greatest separation from the Sun – moments referred to as greatest elongation. On these occasions, however, Venus is so bright and conspicuous that it becomes the third brightest object in the sky after the Sun and Moon. It is often called the morning or evening star. These apparitions take place alternately in the morning and evening skies, depending whether Venus lies to the east of the Sun or to the west.
