The Earth core's inability to turn is mirrored in the cast's inability to give the picture any spin." [12] Kenneth Turan of the Los Angeles Times was a little more forgiving, saying: "If The Core finally has to be classified as a mess, it is an enjoyable one if
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius. [1] [2] There are no samples of the core accessible for direct measurement, as there are for Earth's mantle. [3]
All of the rocky inner planets, as well as the moon, have an iron-dominant core. Venus and Mars have an additional major element in the core. Venus’ core is believed to be iron-nickel, similarly to Earth. Mars, on the other hand, is believed to have an iron-sulfur core and is separated into an outer liquid layer around an inner solid core.

The magnetic field of a magnetic dipole has an inverse cubic dependence in distance, so its order of magnitude at the earth surface can be approximated by multiplying the above result with (R outer core ⁄ R Earth) 3 = (2890 ⁄ 6370) 3 = 0.093 , giving 2.5×10 −5 Tesla, not far from the measured value of 3×10 −5 Tesla at the equator.
The core of the Sun is considered to extend from the center to about 0.2 of the solar radius (139,000 km; 86,000 mi). [1] It is the hottest part of the Sun and of the Solar System. It has a density of 150,000 kg/m 3 (150 g/cm 3) at the center, and a temperature of 15 million kelvins (15 million degrees Celsius; 27 million degrees Fahrenheit). [2]
Philolaus has been called one of "the three most prominent figures in the Pythagorean tradition" [4] and "the outstanding figure in the Pythagorean school", who may have been the first "to commit Pythagorean doctrine to writing". [5] Most of what is known today about the Pythagorean astronomical system is derived from Philolaus's views. [8]
Five planets are going to be retrograde in the summer of 2024. Here are the dates for Mercury retrograde, Venus retrograde, Saturn retrograde, Neptune retrograde, Pluto retrograde and more.
In the Doctor Who episode, "The Runaway Bride", a Racnoss warship is found at the center of the planet. In the 1966 Doctor Who spin-off film "Daleks' Invasion Earth 2150 A.D.", the Daleks have turned Bedfordshire into a giant mine complex, digging a shaft, accessing the Earth's core. They intend to explode a nuclear bomb to destroy the core and ...
