Let’s get straight to the point: the reason why Venus and Mercury don’t have moons is: they are too close to the Sun. Of course, this might not be the only reason, but it’s perhaps the most plausible one, according to scientists.
In the solar system, you will find interesting moons: some examples are Jupiter with Io, Europa, Ganymede and Callisto, Saturn with Titan and Enceladus, Neptune and its Triton, Pluto, and Charon…but no moon has ever succeeded in becoming a moon of Mercury or Venus. To understand why this is, let’s take a look at other planets first, and let’s see how their moons formed or got captured, ending up orbiting around the planets in our solar system.

The planets Mercury and Venus do not have moons of their own, unlike other planets in the Solar System.
As Mercury and Venus are so close to the Sun, their gravitational fields are not strong enough to hold onto any moons that may have formed in the early Solar System.
Although these 2 planets do not have moons, our Solar System is full of other objects that are in orbit around them. The most notable of these objects are a group of asteroids known as the Venus-Mars Trojans. These asteroids are in orbit around the two planets and share their orbits. However, it is really hard to spot Venusian asteroids, because of their close proximity to the Sun. A few searches in the Trojan region of Venus have so far reported no detection of stable Venus asteroids around the L4 and L5 Lagrangian points, called trojans. Most authors concluded that any population of primordial Trojans around Venus would have disappeared by now.
