Which planet in our solar system is the closest to Earth in size?
Venus is most like Earth in terms of mass and size, and it is also the planet closest to Earth, but the two planets are far from identical twins.
Which planet is closest to the Sun?
In addition to being the planet closest to the Sun, Mercury is also the smallest by mass. If you ignore the former planet Pluto, it is also the smallest by surface area, as well. The planet has the most eccentric orbit: at perihelion it is 46,001,200 km from the Sun and at aphelion it is 69,816,900 km.
What does the radius of the Earth mean?
Earth radius is the distance from the center of Earth to a point on its surface. Its value ranges from 6,378 km (3,963 mi) at the equator to 6,357 km (3,950 mi) at a pole. Earth radius is a term of art in astronomy and geophysics and a unit of measurement in both. It is symbolized as R⊕ in astronomy.
What is the mass and radius of the Earth?
Earth’s has a mean radius of 6,371 km (3,958.8 mi), and a mass of 5.97 × 10 24 kg, whereas Jupiter has a mean radius of 69,911 ± 6 km (43441 mi) and a mass of 1.8986×10 27 kg.
What is the circumference of the Earth’s orbit?
The circumference of the Earth’s orbit is approximately 2 pi (6.283185) times the mean radius of its orbit. This radius is also known as the astronomical unit (AU), and is about 1.4959787 x 10 11 meters (m). Therefore, the circumference is about 9.399511 x 10 11 m.
