Answer:The asteroid's average (semimajor axis) distance from the Sun is 1AU.
Explanation: Asteroids are known as small objects which have rocky appearance that orbit the Sun as the planets do, although Asteroids are smaller than the size of planets. An Asteroid that orbit the Sun with the same orbital period like the Earth will have the same semi-major distance like the Earth will have which is One Astronomical Unit(the unit of measurement of the distance between the Sun and the Orbiting Asteroids or Planets), 1 ASTRONOMICAL UNIT =
149597871 KILOMETRES.
