while temperatures in the core reach more than 27 million F (15 million C), driven by nuclear reactions. One would need to explode 100 billion tons of dynamite every second to match the energy produced by the sun, according toNASA.
About 110 Earths would fit across the width (diameter) of the sun. It would take about 1.3 million Earths to fit inside the sun (volume). (see the image above illustrating how many earths fit across the sun’s diameter) Solar Wind NASA explains, The solar wind is created by the outward...

According to NASA the mesosphere begins just above the stratosphere and extends to approximately 53 miles (85 km) high. The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere, with temperatures averaging about minus 130 degrees F (minus 90 degrees C) ...
