Which of the following does not correctly describe the fate of the Sun and the Solar system?
- The Sun is about half way through its 10 billion year life cycle.
- In 3-4 billion years, the Sun will get hotter, and the temperature on Earth will rise enough to boil all oceans away.
- In about 5 billion years, the Sun will become a red giant, and the
Earth may eventually find itself inside the outer envelope of the Sun.
- During the planetary nebula phase, the Sun will blow up as a supernova, and the Earth will be cast off into the interstellar space.
- The ultimate fate of the Earth, if still around, is to circle the dim
white dwarf as an icy chunk of rocks.
