Earth’s atmosphere extends beyond the Moon

According to a new study published in the American Geophysical Union’s (AGU) Journal of Geophysical Research, the geocorona (the luminous part of the outermost region of the Earth’s atmosphere, the exosphere) reaches up to 630,000 kilometers (391,000 miles) away, or 50 times the diameter of our planet. For comparison, the average distance between Earth and the Moon is 384,400 km (238,855 miles). So, the outer edge of Earth’s atmosphere extends far beyond the moon.

Driving Distances on Mars and the Moon: Out-of-This-World-Records

This chart, prepared by NASA illustrates comparisons among the driving distances by various wheeled vehicles on the surface of the planetary bodies other than Earth (as of February 13, 2019, only the moon and Mars). Opportunity rover, which declared dead after record-breaking 15-years on the Martian surface also holds the off-Earth roving distance record after accruing 45.16 kilometers (28.06 miles) of driving on Mars.

Italian astronomer, physicist, engineer, and polymath Galileo Galilei’s (15 February 1564 – 8 January 1642) moon drawings. These were the first realistic images of the Moon, due to Galileo’s training in art and an understanding of chiaroscuro (a technique for shading light and dark) he understood that the shadows he was seeing were actually mountains and craters.
