Star Size Comparison

Carl Sagan: “ The universe is not required to be in perfect harmony with human ambition”

Huge sizes, huge numbers ….

Sometimes we think we are the center of the world ..


The size of astronomical objects are so large and the distances are so great that they quickly exceed human comprehension. Each picture below shows increasingly larger objects as one moves further from the earth.

Inner planets of the solar system. These planets are the most dense in the solar system and, with the exception of Pluto, closest to the sun.

The outer planets (gas giants) of our solar system. They consist largely of frozen gases and are consequently the least dense in the solar system. However due to the extremely large masses they exert very strong gravitational force compared to the inner planets.

Our sun is a middle aged average sized star that has been around for about 5 billion years. it will use up all its fuel in another 4.5 Billion years.

Look at the dot, representing Earth …

The size of our sun (smallest sphere in the lower left) compared to other nearby stars:

Some of the still larger stars. Note that there life span is extremely short (millions of years) compared to our sun because they must burn hydrogen fuel at a prodigious rate to to balance against the incredibly strong gravitational force trying to compact the star because of their huge masses.
