By the time the signal travels across space and reaches Earth, it is only \u2018one-billionth of the one-billionth of 1 Watt!\u2019<\/li><li>Research estimates that more than 1300 Earths can easily fit into Jupiter\u2019s vast sphere. That\u2019s how big the king of the solar system is!&nbsp;<\/li><\/ol>\n\n\n\n<ol class=\"wp-block-list\" start=\"3\"><li>Staying true to its namesake (The name Mercury is after the Roman god of messengers), Mercury is the fastest planet in the entire solar system! It zips around the sun at an average speed of 107,000 miles an hour.&nbsp;<\/li><li>All research and evidence collected, point to the fact that the solar system is approximately 4.5 billion years old.&nbsp;<\/li><li>The hottest planet in the solar system is Venus. Temperatures on the surface of Venus reach a whopping 880<sup>o<\/sup>F (471<sup>o<\/sup>C) during the day.&nbsp;<\/li><li>Light-year is a unit of measurement to measure the distance between different celestial objects. One light-year is equal to about 6 trillion miles (9 trillion kilometers)!<\/li><li>Dark matter is a new discovery. It is a mass that does not emit any energy or light and accounts for as much as 27% of the entire universe.&nbsp;<\/li><li>Dark energy, on the other hand, is a mysterious force that causes the rate of expansion of the universe to accelerate over time. Dark energy accounts for 68% of the universe\u2019s total energy!&nbsp;<\/li><li>The asteroid belt is a region within the solar system that is located between the orbits of Mars and Jupiter. The entire mass of the asteroid belt is just 3% of the total mass of the moon! This is an astronomy fact that has revolutionized our understanding of these celestial objects.&nbsp;<\/li><li>Saturn may be the second-largest planet in our solar system, but it is less dense than water! The planet is 96% hydrogen. It would float if you could build a bathtub big enough for Saturn!&nbsp;<\/li><li>The Milky Way is our home galaxy and estimates to contain more than 100 million stars!&nbsp;<\/li><li>The number of observable galaxies in the universe is only 125 billion.&nbsp;<\/li><li>Neutron stars are one of the most fascinating astronomical objects. These stars are composed of neutrons packed together into a tiny radius. They are the densest class of objects and weigh 1.4 times the mass of our sun.&nbsp;<\/li><\/ol>\n\n\n\n<h4 id=\"one-teaspoon-of-neutron-star-material-would-weigh-more-than-one-trillion-kilograms-this-is-one-of-the-astronomy-facts-that-may-be-beyond-comprehension\" class=\"wp-block-heading\">One teaspoon of neutron star material would weigh more than one trillion kilograms!
