In Newtonian physics they are not following a straight path, therefore they must be accelerating.
However in General Relativity they are following a locally straight path through curved spacetime, therefore they are not accelerating.
The closest point in an orbit is called the perigee, for objects orbiting Earth, or periapsis for objects orbiting other celestial bodies.

No. Beyond Pluto, there are thousands of other objects orbiting the Sun.
Asteroids are the rocky planet remnants orbiting the solar system in the asteroid belt. Collisions between these objects may leave debris that can enter the Earth's atmosphere and become meteorites.
The small lumps orbiting the sun are called asteroids. They are rocky objects that vary in size and are mostly located in the asteroid belt between Mars and Jupiter.

You know that no planets actually orbit the earth right? ...?
it is accelerating.
What orbiting man made objects in space are powered with solar energy
These objects are the remains of cosmic experiences.

No Gravity.

Orbiting stars. We know of eight planets orbiting our Sun, and we know of over 300 planets orbiting other stars.
Acceleration is a change in velocity over a given time. Velocity is speed in a given DIRECTION. #1; A car speeding up It changes from say 30 mph to 60 mph in say , 20 seconds. #2 ; The Earth orbiting the Sun . Its acceleration because the speed is constantly changing AND thedirection of movement is constantly changing; NOT in a straight line.
