9th Grade Earth Science

The sun being the center of our solar system is a well-known fact. It is the largest object in our solar system and all other planets, including Earth, revolve around it. The sun's immense gravitational pull holds the planets in their orbits and provides the energy necessary for life on Earth. Therefore, it is accurate to say that the sun is the center of our solar system.

The core of the sun is extremely hot, with temperatures reaching up to 27 million degrees. This high temperature is necessary for the nuclear fusion reactions that occur in the core, where hydrogen atoms combine to form helium and release enormous amounts of energy. The intense heat and pressure at the core are what sustain the sun's energy output, making it the powerhouse of our solar system.

The statement is false because the sun is actually the largest star in our solar system. It is much larger than any other celestial body in our solar system, including the planets. The sun's immense size and mass allow it to exert a gravitational force that keeps all the planets in orbit around it.

The visible part of the sun is estimated to have a temperature of around 10,000 degrees Fahrenheit. This temperature is based on scientific measurements and observations. The sun's surface, known as the photosphere, emits light and heat that we can see and feel on Earth. This temperature is incredibly hot and is responsible for the sun's intense brightness.

The given answer options 4.6, 5.2, and 6.3 million years ago suggest that the sun was born around that time. However, without further context or information, it is not possible to determine the exact age of the sun.
