Venus Formation: Everything You Need To Know About The Planet's Origin

Most of us are aware of the various stars present in the universe but very few are aware regarding their formation. Still, most of the scientists find it difficult to find out how these stars and planets were formed. Currently, two theories are revolving around their formation.

The first theory - Core Accretion is widely accepted by most of the scientists and researchers. This theory worked well with the formation of terrestrial planets such as Venus but has faced problems while dealing with giant planets. Nearly 4.6 million years ago, the solar system was a cloud of dust and gas known as a solar nebula. Smaller particles tend to come closer and were held by the stronger force of gravity. The solar wind wiped away lighter elements such as hydrogen and helium from the nearby regions, leaving heavy materials to form smaller worlds such as Venus. In this manner, the moon, comets, and asteroids were created.

According to Space.com, the rocky core of the Venus was formed initially, followed by gentle crust and mantle. Venus collected the nebulous pieces that would form its atmosphere. A few studies have shown that if water on young Venus evaporated billions of years ago, the greenhouse levels in the atmosphere would have increased. Space.com reveals that according to NASA, the core accretion suggests that small and rocky worlds should be more common than the massive gas giants.

The second theory is the disk instability model. This theory clumps of dust and gas which are merged together since the beginning of life in the solar system. These clumps have slowly formed a giant planet. The biggest challenge to core accretion was building up the huge gas giants to grab the lighter components of the atmosphere.

According to NASA, Venus is one of the brightest objects in the sky and is also known as Evening and Morningstar. Scientists are still on the way to discover how Venus was formed but according to major studies, Venus was formed through a process named Core Accretion.
