Briefings

A 2026 article describes the early solar system formation 4.6 billion years ago, noting that 9 billion years after the universe's birth, a gas cloud collapsed into the Sun and planets. Earth was initially molten and bombarded by meteorites before cooling. The source provides a brief timeline of this process but lacks specific details on planetary composition, atmospheric conditions, or the exact duration of the cooling phase.

Key points

• A gas and dust cloud collapsed into the Sun and planets approximately 4.6 billion years ago, occurring 9 billion years after the universe's birth.
• Earth was initially a molten landscape bombarded by meteorites for the next few hundred million years before cooling.

Context

This article outlines the initial stages of solar system formation, highlighting the immense timescales involved in planetary creation and early Earth conditions.

Limitations

The evidence is a short excerpt from a 2026 article, limiting specific details on planetary composition, atmospheric conditions, or the exact duration of the cooling phase.
