Some sources state that Earth's equatorial speed is slightly less, or 1,669.8 km/h. [41] This is obtained by dividing Earth's equatorial circumference by 24 hours . However, the use of the solar day is incorrect; it must be the sidereal day , so the corresponding time unit must be a sidereal hour.
[nb 1] Earth's orbital speed averages 29.78 km/s (19 mi/s; 107,208 km/h; 66,616 mph), which is fast enough to cover the planet's diameter in 7 minutes and the distance to the Moon in 4 hours. [3] The point towards which the Earth in its solar orbit is directed at any given instant is known as the "apex of the Earth's way". [4] [5]

The iron-rich core region of the Earth is divided into a 2,440 km (1,520 mi) diameter solid inner core and a 6,960 km (4,320 mi) diameter liquid outer core. [69] The rotation of the Earth creates convective eddies in the outer core region that cause it to function as a dynamo. [70]
Texas is the second-largest U.S. state by area, after Alaska, and the largest state within the contiguous United States, at 268,820 square miles (696,200 km 2). If it were an independent country, Texas would be the 39th-largest . [ 148 ]
