How big is the Earth

Earth, our humble abode, a minuscule blue speck adrift in the vast cosmic sea where every person you've ever known, every human who has ever existed, and every tale ever recounted resides. It is the starting point of our journey, but as we venture beyond our atmosphere, past the moon, and further away, we embark on a grand adventure. Our quest is to comprehend the true expanse of the universe. The moon, our first stop, lies about 384,000 km away. The distance is so immense that if you were to drive a car at a steady speed of 100 km per hour, it would take over 160 days to reach it. From the lunar vantage point, Earth appears as a delicate sphere of blues and greens nestled in the vast darkness of space, offering a humbling view of our existence. As we progress outward, the sun becomes our next milestone, approximately one astronomical unit away from Earth. This unit, equivalent to about 150 million km, serves as the standard measure for distances in our solar system. The light, traveling at an astonishing speed of 300,000 km/s, takes about 8 minutes and 20 seconds to journey from the Sun to Earth. If you were to cover this distance in a commercial jet flying at 900 km per hour, it would take approximately 19 years. This immense gap serves as a stark reminder of the vastness of space even within our solar system. The sun, a blazing giant, provides vital energy to our planet from this incredible distance. Moving beyond Earth and its solar companion, we turn our attention to Mars, our mysterious red neighbor. At its closest point to Earth, Mars is about 54.6 million km away. However, this distance can extend up to 401 million km when the two planets are on opposite sides of the sun. To put it into perspective, traveling to Mars at the speed of a commercial jet would take over 50 years. The vast space between Earth and Mars is a significant reminder of the immense distances in our solar system.
