Interesting fact: Venus is often called Earth's 'sister planet' because of their similar size and mass, yet its surface conditions are extremely hostile.
The answer: Venus has a mass of about 4.87 × 10^24 kilograms, which is approximately 0.815 times the mass of Earth.
Venus is the second planet from the Sun and is similar in size and mass to Earth, making it one of the terrestrial planets. Despite this similarity, Venus has a thick, toxic atmosphere and surface temperatures hot enough to melt lead. Its mass influences its gravity and atmospheric retention. Studying Venus helps scientists understand planetary atmospheres and the potential for climate extremes.
