A learner says that Earth rotates on its axis as it revolves around the sun in a circular orbit and that the sun is at the exact
center of this orbit. What mistake did the learner make? Explain the mistake in detail. Your answer should include at least two complete sentences. Be sure to check your grammar and spelling.
The earth’s orbit around the sun is a perihelion. The orbit is also not a true elliptic circle because the orbit is influenced by other nearby celestial orbits such as the planets in the solar system. On occasion, the orbit is deformed putting a particular part of the earth’s orbit closer to or farther from the sun. Also, the barycentre of the solar system changes as the alignment of the solar system’s celestial bodies varies over time.
