Mysterious Atmosphere of Venus

Venus has an incredibly thick atmosphere, composed mostly of carbon dioxide, which traps heat in a powerful greenhouse effect.
The Venusian clouds are primarily made of sulfuric acid, which is highly corrosive and dangerous.
The atmosphere on Venus is nearly 90 times denser than Earth’s, making surface conditions similar to being 1,500 meters underwater.
Despite its cloud cover, Venus experiences a slight yellowish-orange color due to reflected sunlight.
Venus has no magnetic field, unlike Earth, leaving its atmosphere more vulnerable to solar winds.

Venus’ Unique Orbital and Rotational Properties

Venus rotates in the opposite direction of most planets, including Earth – a phenomenon called retrograde rotation.
A day on Venus (243 Earth days) is longer than its year (225 Earth days).
