Test: Solar System - 2 - Class 1 MCQ

Venus is often referred to as the evening/morning star. This is because Venus is one of the brightest objects in the sky and can be seen shortly before sunrise or after sunset. Its brightness and visibility have earned it the title of the evening/morning star, even though it is not a star but a planet.

Ganymede, the biggest moon in our solar system, belongs to Jupiter. Ganymede is not only Jupiter's largest moon but also the largest moon in the entire solar system. It is even larger than the planet Mercury. Ganymede has a subsurface ocean and a thin atmosphere.

Neptune has 14 known moons as of my knowledge cutoff in September 2021. Triton, Neptune's largest moon, is one of the most interesting moons in the solar system due to its retrograde orbit and geysers of nitrogen erupting from its surface.

Uranus has 27 known moons as of my knowledge cutoff in September 2021. Some of its notable moons include Titania, Oberon, Umbriel, Ariel, and Miranda.

Titan is one of the moons of Saturn. Titan is Saturn's largest moon and the second-largest moon in the solar system. It is known for its thick atmosphere and has features similar to Earth, including lakes, rivers, and even rain, although composed of methane and ethane.

Phobos and Deimos are the natural satellites of Mars. They are small, irregularly shaped moons that orbit Mars. Phobos is the larger of the two and is closer to Mars, while Deimos is smaller and farther away.

The planet with two moons is Mars. Mars has two natural satellites called Phobos and Deimos. They are irregularly shaped and are thought to be captured asteroids.

The planet(s) with no moons is/are Mercury and Venus. Mercury, the closest planet to the Sun, and Venus, the second planet from the Sun, do not have any moons.

According to the NASA/JPL Solar System Dynamics team, the current tally of moons orbiting planets in our solar system is 290: One moon for Earth; two for Mars; 95 at Jupiter; 146 at Saturn; 27 at Uranus; 14 at Neptune; and five for dwarf planet Pluto.

A celestial body in space that orbits around a larger body is called a natural satellite. Natural satellites are objects that revolve around planets, dwarf planets, or asteroids under the influence of their gravitational force.
