How many Earths can fit in the sun?
1.3 million Earths
If you divide the volume of the sun by the volume of the Earth, you get that roughly 1.3 million Earths can fit inside the sun.
Who named the Earth?
The answer is, we don’t know. The name “Earth” is derived from both English and German words, ‘eor(th)e/ertha’ and ‘erde’, respectively, which mean ground. But, the handle’s creator is unknown.

Why is Earth called a terrestrial planet?
The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth’s terra firma. The terrestrial planets are the four innermost planets in the solar system. Without life, most of the oxygen would soon become part of the compounds on the planet’s surface.
How many years is Pluto’s orbit?
248 years
Pluto/Orbital period
Orbit and Rotation Pluto’s 248-year-long, oval-shaped orbit can take it as far as 49.3 astronomical units (AU) from the Sun, and as close as 30 AU. (One AU is the mean distance between Earth and the Sun: about 93 million miles or 150 million kilometers.)
How many Saturns fit in the Sun?
Saturn has a diameter of approximately 120.536 km / 74.897 mi and a radius of around 58.232 km / 36.183 mi. It is quite massive as well, having the equivalent of 95.16 Earth masses. It would take more than 1,700 Saturn-sized planets to fill the Sun.
