What is the Earth's only natural satellite?

Phobos
Moon
Europa
Deimos

The correct answer is: Moon

The Earth's only natural satellite is the Moon. It is a unique celestial body that orbits the Earth and is the fifth largest moon in the solar system. The Moon's significance extends beyond its physical characteristics; it has a profound influence on Earth, impacting tides and the planet's axial tilt, which affects climate and seasons. Phobos and Deimos, on the other hand, are natural satellites of Mars, not Earth, and Europa is one of Jupiter's moons. This distinction is essential, as it highlights the Moon's role specifically in Earth's orbit and its relationship with our planet compared to the other celestial bodies, which belong to different planetary systems.
