What is the estimated amount of matter falling on the sun annually to maintain its heat?
Understand the Problem
The question is asking for an estimation of the amount of matter that falls onto the sun each year in relation to its mass, with multiple-choice options provided. This requires knowledge in astrophysics and the estimation of solar phenomena.
Answer
The Sun's heat is primarily maintained by nuclear fusion, not external matter.
There is no specific amount of matter falling onto the Sun annually required to maintain its heat provided in the search results. The Sun's energy is mainly sustained by nuclear fusion of hydrogen atoms in its core.

More Information
The Sun generates its energy through nuclear fusion, where hydrogen nuclei combine to form helium, releasing immense energy. Any matter falling into the Sun, such as comets or meteorites, is negligible in comparison to the energy output from fusion.
Tips
A common misconception is assuming the Sun requires external matter to maintain its energy when nuclear fusion suffices.
