According to astronomers, the Earth should last for at least 5 billion (5×10⁹) more years before the sun becomes a red giant. Due to the sun's loss of mass the Earth would escape to an orbit at a further distance than its current orbit. The immense heat however would likely boil off the oceans and turn the Earth into a barren wasteland looking like Mars does with a similar climate to Venus. Irrespective of the Earth surviving that event, the sun will have further evolved into a white dwarf and provide too little heat to sustain life. Sol redirects here. ... According to the Hertzsprung-Russell diagram, a red giant is a large non-main sequence star of stellar classification K or M; so-named because of the reddish appearance of the cooler giant stars. ...

Others say the atmosphere will lose its water vapor into space within 1.1 billion years because the sun will become about 10% hotter, and that the oceans will evaporate within 3.5 billion years when the sun is 40% hotter. Arthur C Clarke once coined the term "sungevity" to put a name to the period, which is as long as life as we know it can exist, at least on this planet. Air redirects here. ...

In 3.5 billion years (3.5×10⁹) the Andromeda Galaxy will collide with the Milky Way Galaxy, though given the vastness of interstellar space, few solar systems would be directly affected. Most scientists, however, believe that our solar system will escape unharmed, though there is a chance that it may be ejected from the merging galaxies altogether. The Andromeda Galaxy (IPA: , also known as Messier 31, M31, or NGC 224; older texts often called it the Great Andromeda Nebula) is a spiral galaxy approximately 2. ... The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia Kuklos; or simply the Galaxy) is a barred spiral galaxy in the Local Group, and has special significance to humanity as the location of the solar system, which is located near the Orion...

The end of planet Earth is not necessarily synonymous with the extinction of humanity. Just as it is possible for the Earth to outlive humanity, it is also possible for humanity in the future to find other places to live—and, perhaps, outlive the Earth.
