About this document
The Future of Life on Earth: Solar Evolution by Alyssa Harper is a document available to read on EtoBox.
The document summarizes the future evolution of Earth and the Sun over billions of years. It describes that the Sun will expand into a red giant in about 7.5 billion years, likely engulfing Earth, after it exhausts its hydrogen fuel. The Sun will then contract briefly and expand into a second red giant phase, before ejecting its outer layers and becoming a white dwarf. Over hundreds of billions of years, any remnants of Earth will orbit the cooling white dwarf until the end of the universe.
