It's a star but not!

The star blinks and moves across the horizon at night. It blinks like an airplane but dosnt move! Now if you walk away and come back and look again it's moved it moves to the right in a straight line. Iv seen this at night during the winter months for about 4 years now. It used to be right in front of my house this year its further down the beach but it's still here! Iv tried recording it dosnt work my phone can't pick it up.
