Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 × 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
[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 ] From a vantage point above the north pole of either the Sun or Earth, Earth would appear to revolve in a counterclockwise direction around the Sun.
Earth orbits the Sun, making Earth the third-closest planet to the Sun and part of the inner Solar System. Earth's average orbital distance is about 150 million km (93 million mi), which is the basis for the astronomical unit (AU) and is equal to roughly 8.3 light minutes or 380 times Earth's distance to the Moon .
UY Scuti was analyzed to be the largest and the most luminous of the three stars measured, at 1,708 ± 192 R ☉ (1.188 × 10 9 ± 134,000,000 km; 7.94 ± 0.89 AU) based on an angular diameter of 5.48 ± 0.10 mas and an assumed distance of 2.9 ± 0.317 kiloparsecs (kpc) (about 9,500 ± 1,030 light-years) which was originally derived in 1970 ...
Geodesy. Earth's circumference is the distance around Earth. Measured around the equator, it is 40,075.017 km (24,901.461 mi). Measured passing through the poles, the circumference is 40,007.863 km (24,859.734 mi). [ 1] Measurement of Earth's circumference has been important to navigation since ancient times. The first known scientific ...
Details. Earth is the third planet from the Sun with an approximate distance of 149.6 million kilometres (93.0 million miles), and is traveling nearly 2.1 million kilometres per hour (1.3 million miles per hour) through outer space. [ 11]

This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [105] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [110] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus A (α Leonis) 4.35 ± 0.1 [105]
