It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration. Also, the speed of light is a constant, which means it does not change.
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
At the point when it is closest to the sun.

No. An object traveling at a constant velocity is not accelerating.
You can be accelerating and traveling at a constant speed if you change directions.
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
When something is traveling at a constant velocity it has no acceleration. In other words your answer is 0.
If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
Your body cannot sense constant velocity. For example, you cannot sense that the earth is turning nor can you sense that the earth is orbiting around the sun. And, if you are in a vehicle that is traveling with a constant velocity, you cannot sense that you are moving unless your eyes sense a change in position.

0. "Constant speed" means it is not accelerating.
