What is the deferent of destance sun from earth in 1100 and 2012?

Answer 1

The average distance from the Sun to Earth is about 93 million miles (150 million kilometers), and this distance remains relatively constant over time due to Earth's slightly elliptical orbit. So, the distance between the Sun and Earth would be roughly the same in the years 1100 and 2012. Any perceived variations would be due to normal fluctuations in Earth's orbit rather than any significant long-term change.
