Infact
89 / 100
True Venus

Venus has a day longer than its year, taking 243 Earth days to rotate and 225 days to orbit the Sun. It rotates opposite to most planets, causing the Sun to rise in the west and set in the east.

Infact verdict: True (89/100).

The claims about Venus's rotation and orbit are well-supported by both fact-checks and authoritative sources. Snopes confirms that a day on Venus is longer than a year, and multiple sources, including NASA, corroborate the specific rotation and orbit periods. Venus's retrograde rotation is also well-documented, explaining the unusual sunrise and sunset directions.
