The mean distance of the earth from the sun is approximately

The correct answer is A. 149,502,000 km.

The Earth’s orbit around the Sun is not a perfect circle, but an ellipse. This means that the Earth’s distance from the Sun varies throughout the year. The Earth’s closest approach to the Sun is called perihelion, which occurs in January. The Earth’s farthest distance from the Sun is called aphelion, which occurs in July.

The mean distance of the Earth from the Sun is the average of the Earth’s perihelion and aphelion distances. This distance is approximately 149,502,000 km.

Option B is incorrect because it is the Earth’s aphelion distance. Option C is incorrect because it is the Earth’s perihelion distance. Option D is incorrect because it is not the Earth’s mean distance from the Sun.
