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 Ă 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
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. Earth orbits the Sun every 365.2564 mean solar days, or one sidereal year. With an apparent movement of the Sun in Earth's sky at a rate ...
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 measurement and calculation was done by Eratosthenes, by comparing ...
NASA/JPL-Caltech/R. Hurt. A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, according to a new study. The planet is ...
Earth radius (denoted as Rđ¨ or ) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid, the radius ranges from a maximum of nearly 6,378 km (3,963 mi) ( equatorial radius, denoted a) to a minimum of nearly 6,357 km (3,950 mi) ( polar radius, denoted b ).
NASA just announced that they've found 219 potential planets, and of those, 10 are close to the size of Earth and could possibly sustain life. NASA finds evidence of 10 new Earth-size planets that ...
Dymaxion world map with continental landmasses (I,II,III,IV) and largest islands (1â30) roughly to scale. This list includes all islands in the world larger than 2,500 km 2 (970 sq mi) and most of the islands over 1,000 km 2 (390 sq mi), sorted in descending order by area.
The Earth and the Moon will most likely be destroyed by falling into the Sun, just before the Sun reaches the largest of its red giant phase when it will be 256 times larger than its current size. Before the final collision, the Moon will possibly spiral below Earth's Roche limit , breaking into a ring of debris, most of which would fall to ...
