Are you asking if the laws of physics cease to exist outside of the solar system? Short answer... No. But don't stop being curious.
Gravity is gravity. One object with mass attracts any other object with mass with a force proportional to their masses and inversely proportional to the distance between them. While kind of pointless, you could calculate the gravitational force between Alpha Centuri and my computer mouse. There are plenty of things between that are exerting more force, but that doesn't make the force zero. Close enough to zero that is doesn't matter? Sure. But it's not zero.
The sun is always exerting a gravitational force on the Parker Solar Probe. That's what causes it to orbit instead of just shoot past the sun in a straight line. As the probe approaches the sun, it accelerates due to the gravitational force and the velocity being similar in direction. Once the probe passes its closest distance from the sun, the velocity vector starts pointing away from the sun while gravity pulls towards it. This causes the probe to decelerate until it reaches its farthest point from the sun.
The speed of light is a constant. It's the fastest speed in the universe. That doesn't change when you're on earth, out near Pluto, in interstellar space, or in intergalactic space.
no its not...gravity is gravity.. all depeding on ur closest mass. Unless your talking about the gravity of our star being weaker at the ort cloud tugging on objects...then yes.

I hope this helps.
