The Tycho Crater is always facing Earth due to a phenomenon known as synchronous rotation, or tidal locking. This is a condition that occurs when an astronomical body rotates on its axis in the same amount of time it takes to orbit another body.
In the case of the Moon, it takes about 27.3 days to rotate once on its axis, which is the same amount of time it takes to complete one orbit around Earth. As a result, only one side of the Moon is ever visible from Earth, and this side includes the prominent Tycho Crater.
The craters themselves, like Tycho, were formed by the impact of meteoroids and asteroids striking the Moon’s surface. Over billions of years, the Moon has remained in this locked position, and thus features like Tycho have an eternal view toward Earth, while the far side remains hidden from our line of sight.
So, the reason we can always see Tycho (and other features) is simply because of the Moon’s rotation and orbit being synchronized with its revolution around Earth, creating a captivating celestial view for us!
