In a heliocentric system, Earth revolves around THE SUN

HELIOS (or Helius) was the Titan god of the sun. He was also the guardian of oaths and the god of gift

of sight. Helios dwelt in a golden palace located in the River Okeanos at the eastern ends of the earth.

From there he emerged each dawn driving a chariot drawn by four, fiery winged steeds and crowned

with the aureole of the sun. When he reached the the land of the Hesperides (Evenings) in the West he

descended into a golden cup which carried him around the northern streams of Okeanos back to his

rising place in the East. Once his son Phaethon attempted to drive the chariot of the sun, but losing control, set the earth on fire. Zeus then struck him

down with a thunderbolt.

What does GEOCENTRIC mean?

Geo= earth centric= centeredThe Geocentricmodel of our solarsystem ERRONEOUSLY places the Earth at the center of the solar system. This was proven to be wrong and was replaced with the Heliocentric model.

How large is the moon compared to Earth?

How large is the moon compared to Earth?

about one-fourth the diameter of Earth Random fact: 99% of the

time when you see a picture of earth it is THIS picture. I know this because, as a

kid, my room had this picture wallpapered on it taking up the WHOLE

wall. I always saw Chewbacca’s

face in the clouds.

What is distinctive about Jupiter?

What is distinctive about Jupiter? It is the largest and most massive

planet.

Jupiter, the most massive planet in our solar system -- with dozens of moons and an enormous magnetic field -- forms a kind of miniature solar system. Jupiter does resemble a star in composition, but it did

not grow big enough to ignite. The planet's swirling cloud stripes are punctuated by massive storms such as the Great Red Spot, which has

raged for hundreds of years.

Name the planets of our solar system IN ORDER from the sun

outward.

Which is the smallest planet in our solar system?

Which is the smallest planet in our solar system?

MERCURYIn Roman mythology Mercury is the god of commerce, travel and thievery,

the Roman counterpart of the Greek god Hermes, the messenger of the Gods. The planet probably received this name because it moves so quickly across the sky.

Until 1962 it was thought that Mercury's "day" was the same length as its "year" so as to keep that same face to the Sun much as the Moon does to the Earth. But this was shown to be false in 1965 by doppler radar observations. It is now known that Mercury rotates three times in two of its years.

Temperature variations on Mercury are the most extreme in the solar system ranging from 90 K to 700 K. Read more about Mercury  l  Mercury facts, pictures and information. by nineplanets.org

Because Pluto did not clean its room (orbit)

A "planet" is a celestial body that

(a)is in orbit around the Sun,

(b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes

a hydrostatic equilibrium

(nearly round) shape, and

(c) has cleared the neighborhood around its orbit.
