If the object does not appear to move, then it is likely a star. The blinking or twinkling you see is called scintillation, and happens when the star’s light passes through the Earth’s atmosphere. Differing air densities of the atmosphere make the light appear to twinkle. This effect is strongest closest to the horizon, as the light must pass through more of the atmosphere than it would directly overhead.
