The biggest member of the solar system is

The biggest member of the solar system is the Sun. The Sun is a star located at the center of the solar system and is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the solar system and is approximately 109 times bigger than the Earth. The Sun's diameter is about 1.39 million kilometers, which is more than 100 times bigger than the diameter of the Earth. Its huge mass and size make it the dominant force in the solar system, holding all the planets in orbit around it through the force of its gravity. The Sun is also the source of most of the energy that drives the Earth's climate and weather patterns. Its heat and light provide energy for life on Earth and are essential for photosynthesis in plants. Without the Sun, life on Earth would not be possible.
