1. Mercury has no atmosphere: While it has a very thin exosphere, it is often described as having “no atmosphere” in simpler terms because it lacks a significant gaseous envelope compared to other planets. This statement is considered correct in this context.
2. Venus has two moons: This is incorrect. Venus has no moons.
3. There is no land on Jupiter: This is correct. Jupiter is a gas giant without a solid surface; it’s composed primarily of hydrogen and helium, transitioning to denser states towards the core.
4. Rings of Saturn are composed of lumps of ice and dust: This is correct. Saturn’s prominent rings are made up of countless particles, predominantly water ice, ranging in size from micrometers to several meters.
