<span>Before we can use parallax to measure the distance to a nearby star, we first need to know the Earth-Sun distance.
Not before we find out what the distance between our planet and the Sun is can we use the parallax to measure the distance to a nearby star.

Answer:
yes for both.
Explanation:
according to Newton's first law an object in motion will stay in motion until acted on by an outside force and an object at rest will stay at rest until acted on by an outside force. this means that an object that is moving will stay moving in the direction that it's moving and at the same speed unless there's an outside force acting on it and it will keep in motion until there is an outside force acting on it.
