By 3.5 billion years from now, Earth's surface conditions will be similar to those of Venus today. [117] Relative size of the Sun as it is now (inset) compared to its estimated future size as a red giant. Around 5.4 billion years from now, the core of the Sun will become hot enough to trigger hydrogen fusion in its surrounding shell. [118]
NASA's Wilkinson Microwave Anisotropy Probe (WMAP) project's nine-year data release in 2012 estimated the age of the universe to be (13.772 ± 0.059) × 10 9 years (13.772 billion years, with an uncertainty of plus or minus 59 million years). [22]
The timeline of the early universe outlines the formation and subsequent evolution of the Universe from the Big Bang (13.799 ± 0.021 billion years ago) [1] to the present day. An epoch is a moment in time from which nature or situations change to such a degree that it marks the beginning of a new era or age .
The millions of years that followed were a bit of a growth spurt for Jupiter as it began to draw in more and more gas and balloon up to its current mass which is over 300 times that of Earth.
Mars reaches the same solar flux as that of the Earth when it first formed 4.5 billion years ago from today. [92] < 5 billion The Andromeda Galaxy will have fully merged with the Milky Way, forming an elliptical galaxy dubbed "Milkomeda". [95] There is also a small chance of the Solar System being ejected. [95] [108] The planets of the Solar ...
Based on Jupiter's composition, researchers have made the case for an initial formation outside the molecular nitrogen (N 2) snow line, which is estimated at 20–30 AU (3.0–4.5 billion km; 1.9–2.8 billion mi) from the Sun, and possibly even outside the argon snow line, which may be as far as 40 AU (6.0 billion km; 3.7 billion mi).
Planetary scientists have, for instance, struggled to explain how a major collision created the moon 4.35 billion years ago, at a time in the solar system’s history when most large celestial ...
