SOLAR SYSTEM

Detailed explanation-1: -Yet Earth remains a standout, and so far, one of a kind. Of the thousands of exoplanets – planets around other stars – confirmed by our increasingly powerful telescopes, and despite extensive probing of the solar system, ours is still the only planet known to host life.

Detailed explanation-2: -A: Earth is considered to be in area known as the “Goldilocks Zone” around our Sun. It is just the right distance away from our Sun to allow just the right amount of air, water and heat to support life.

Detailed explanation-3: -The severe surface temperatures on Venus, which reach about 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, make water-based life as we know it on the planet’s surface implausible.

Detailed explanation-4: -To date, no proof of past or present life has been found on Mars. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms, but habitable conditions do not necessarily indicate life.
