Question

How much old is our earth ?​

Answer 1

Explanation:

Although the universe is thought to be about 13.77 billion years old, planet Earth is much younger than that. Current estimates put the age of Earth at around 4.54 billion years, give or take about 50 million years, and like all other bodies in the solar system, Earth formed when a cloud of dust and gas collapsed due to gravity. This means our sun, planets, asteroids and moons are also around the same age.
