So far, they have been able to go about 12 miles deep, 1/5th of the crust.
The Earth's radius is approximately 6,371 kilometers and 3,959 miles.
It is about 3,961.3 miles, or 6,378.1 kilometers
The distance from Jupiter to Earth varies between about 365 million miles (588 million kilometers) and 601 million miles (967 million kilometers), depending on their positions in their orbits. The distance from Saturn to Earth ranges from about 746 million miles (1.2 billion kilometers) to 848 million miles (1.4 billion kilometers). The distance from Uranus to Earth varies from about 1.6 billion miles (2.6 billion kilometers) to 1.9 billion miles (3.1 billion kilometers).
Miles or kilometers
Apogee (farthest point from Earth) - 251,968 miles or 405,503 kilometers Perigee (closest to Earth) - 221,463 miles or 356,334 kilometers Average Distance - 238,857 miles or 384,392 kilometers
The troposphere extends about 7 miles (11 kilometers) above Earth's surface at the poles and about 12 miles (19 kilometers) at the equator.
The circumference of the Earth at the equator is 40,075 kilometers or 24,902 miles. The circumference of the Earth through the poles is 40,008 kilometers or 24,860 miles.
The Earth's equatorial circumference is approximately 24,901 miles.
The average distance from Earth to the moon is about 384,400 kilometers (238,855 miles). So, the total distance from Earth to the moon and back would be approximately 768,800 kilometers (477,710 miles).
Mercury is about 48000000 miles (77300000 kilometers) from Earth at its closest
The exosphere begins around 310 miles (500 kilometers) above Earth's surface and extends out to about 6,200 miles (10,000 kilometers).
The average distance from Earth to the Moon is about 238,855 miles (384,400 kilometers). This distance can vary slightly due to the Moon's elliptical orbit around the Earth, ranging from approximately 225,623 miles (363,104 kilometers) at its closest (perigee) to about 252,088 miles (405,696 kilometers) at its farthest (apogee).
