A method for automatic navigation and parking of a vehicle (202) in a tight parking space using a navigation system (200) is provided. The method includes identifying a vacant slot (406C) in a designated area (204) and stopping the vehicle (202) at a current position (412) within the designated area (204) upon identifying the vacant slot (406C). The method further includes determining a linear distance by which the vehicle (202) has to initially move from the current position (412) to a start point (426) for ultimately reaching a destination point (418) within the vacant slot (406C) via a middle point (438) and a tangential point (422). The navigation system (200) determines the linear distance based on a horizontal distance between the tangential point (422) and a collinear point (436) and one or more coordinates of the tangential point (422), the start point (426), and the current position (412).
