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). Measurement of Earth's circumference has been important to navigation since ancient times.
Earth radius (denoted as RšØ 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 ).
The second-tallest structure in the world is the 679-metre-tall (2,227 ft) Merdeka 118 in Kuala Lumpur, Malaysia, while the third-tallest self-supporting structure and the tallest tower in the world is the Tokyo Skytree (634 m or 2,080 ft). The tallest guyed structure is the KRDK-TV mast in North Dakota, U.S. at 630 metres (2,060 ft).
The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...
The distance separating the planet and its star is just 7% of the distance between Earth and the Sun, and the planet receives 1.6 times more energy from its star than Earth does from the Sun.
The average diameter of the orbit of the Earth relative to the Sun. Encompasses the Sun, Mercury and Venus. Inner Solar System ~6.54 AU 9.78Ć10 8: 8.99: Encompasses the Sun, the inner planets (Mercury, Venus, Earth, Mars) and the asteroid belt. Cited distance is the 2:1 resonance with Jupiter, which marks the outer limit of the asteroid belt.
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 ...
Impact event. Damage to trees caused by the Tunguska event. The object, just 50ā80 metres (150ā240 feet) across, exploded 6ā10 km (4ā6 miles) above the surface, shattering windows hundreds of km away. An impact event is a collision between astronomical objects causing measurable effects. [1]
