It has the longest rotation period (243 Earth days) of any planet in the Solar System and rotates in the opposite direction to most other planets (meaning the Sun rises in the west and sets in the east). It does not have any natural satellites. It is named after the Roman goddess of love and beauty. It is the second-brightest natural object in the night sky after the Moon, reaching an apparent magnitude of 4.6 bright enough to cast shadows at night and, rarely, visible to the naked eye in broad daylight. Orbiting within Earth's orbit, Venus is an inferior planet and never appears to venture far from the Sun; its maximum angular distance from the Sun (elongation) is 47.8°.", 'Venus is the second planet from the Sun, orbiting it every 224.7 Earth days.', 'Venus is the second planet from the Sun, orbiting it every 224.7 Earth days.

Because its rotation is so slow, Venus is very close to spherical. A Venusian sidereal day thus lasts longer than a Venusian year (243 versus 224.7 Earth days). Venus\'s equator rotates at , whereas Earth\'s rotates at . Venus\'s rotation has slowed down in the 16\xa0years between the "Magellan" spacecraft and "Venus Express" visits; each Venusian sidereal day has increased by 6.5\xa0minutes in that time span. Because of the retrograde rotation, the length of a solar day on Venus is significantly shorter than the sidereal day, at 116.75\xa0Earth\xa0days (making the Venusian solar day shorter than Mercury\'s 176\xa0Earth\xa0days). One Venusian year is about 1.92\xa0Venusian solar days.
