Which planet has no moons?

In our solar system, two planets have no natural moons: Mercury and Venus.

Both of these planets orbit very close to the Sun, and this plays a major role in why they don’t have satellites.

Here’s the reasoning:

• The Sun’s strong gravitational pull makes it difficult for nearby planets to capture or retain moons
• Any potential moon could either be pulled away by the Sun or fail to remain in a stable orbit

Additional context:

• Mercury is the smallest planet and closest to the Sun
• Venus, despite being similar in size to Earth, also lacks any natural satellite

Conceptual takeaway: The presence or absence of moons is influenced by factors like gravitational forces, distance from the Sun, and planetary formation history.
