Earth radius (represented as R🜨 or R E {\displaystyle R_{E}} ) is the distance from the center of Earth to a point on or near its surface. Approximating...
two parts, a "solid" inner core with a radius of ≈1,220 km and a liquid outer core extending beyond it to a radius of ≈3,400 km. The densities are between...
Earth is the third planet from the Sun in the Solar System. It is the only planet known to have life on it. The Earth formed about 4.6 billion years ago...

such a new moon. The brightness of the earthshine is [ Earth albedo × (Earth radius / Radius of Moon's orbit)² ] relative to the direct solar illumination...- inner core is the very center of the Earth, and the hottest part of the planet. It is a mainly a solid ball with a radius of about 1,220 km (760 mi), according...
light years from Earth in the Grus constellation. It has 5.4 times the mass of Earth, and has a radius of 1.5 times Earth's radius. The planet is thought...- in that order. The radius of the semi-major axis (the distance from the center of Earth to the outside at the equator line) of Earth at the equator is...

and 58 minutes. Each circle is 26,600 kilometres (16,500 mi) radius due to the Earth's radius. Far from the North Pole and South Pole, a GPS unit can receive...

This has the effect of slightly increasing...
- the Earth's. A core's size can vary from each planet or other object. The moon's core is 20% of its radius, but Mercury's core is 75% of its radius....
fixed distance from the center. The distance from the center is called the radius of the sphere. When the sphere is filled in with all the points inside,...
blue star with 13–25 times the Solar radius. If VV Cephei A were placed in the center of our Solar System, its radius would reach past the orbit of Mars...
existence of Kepler-22b was announced. Kepler-22b's radius is roughly 2.4 times the radius of Earth. Its mass and surface composition remain unknown, with...

AU in about 8.317 minutes. From 1976 to 2012 the AU was defined as “the radius of an unperturbed circular Newtonian orbit about the Sun of a particle having...- is likely a hot super-Earth or mini-Neptune. It is 2.24 times the radius of the Earth and 4.48 times the diameter of the Earth. Barclay, Thomas; et al...
criteria: Earth Similarity Index (ESI) — Similarity to Earth on a scale from 0 to 1, with 1 being the most Earth-like. ESI depends on the planet's radius, density...
