The Sun closest to Earth is our own Sun, which is located about 93 million miles away. The next closest star system to Earth is Alpha Centauri, which is about 4.37 light years away, much closer than 4500 light years.
The BFB2004 VV 29 1561 galaxy (one of the background galaxies of the Tadpole Galaxy) is a spiral galaxy 4500 million light-years (redshift of 0.43) from Earth in the Draco constellation, and is 60,000 light-years in diameter (1.7 times smaller than the Milky Way), and contains about 40 billion stars (40 percent of the Milky Way's stars). It emitted its light 4500 million years ago, when the universe was 9200 million years old.
The BFB2004 VV 29 4283 galaxy (one of the background galaxies of the Tadpole Galaxy) is a spiral galaxy 4500 million light-years (redshift of 0.42) from Earth in the Draco constellation, and is 60,000 light-years in diameter (1.7 times smaller than the Milky Way), and contains about 40 billion stars (40 percent of the Milky Way's stars). It emitted its light 4500 million years ago, when the universe was 9300 million years old.
The oldest fossils found are considered to be from the late Archean period which ended 2500 million years ago. By contrast, the Earth is believed to be 4500 million years old. So, though both dates are amazingly old, the Earth is definitely older than the fossils.
0.45 percent of one million = 4500 0.45% of 1000000 = 0.45% * 1000000 = 0.0045 * 1000000 = 4500
The percentage of carbon dioxide in the atmosphere has varied significantly over the last 4500 million years. There have been periods with much higher CO2 levels, such as during the early Earth with levels over 100 times higher than today, and periods with much lower levels, like during the last ice age around 20,000 years ago. However, the rapid increase in CO2 levels over the past century due to human activities is unprecedented in Earth's history.
