What are the similarities between heliocentric and geocentric?

Answer 1

Heliocentrism is the astronomical theory that the Earth and planets revolve around the Sun and that the Sun is stationary at the center. The geocentric model is the theory that the Earth is the center of the universe and other objects go around it.

Answer 2

According to what I have learned, the similarities of the two theories are the ff:

a) They are stating which celestial body is the center of the system;and

b) The sun, earth,moon, and other planets are present.

Answer 3

Geocentric means Earth centered, heliocentric means Sun centered. These terms are usually used in Astrology but can be used in Astronomy as well. If this is an astrology question they are alike in that because the plants can seem to be going around the earth when they are in fact going around the Sun. This is because the Earth is close to the center of the solar system. The further out the planets like Neptune and Pluto, the less difference there is between heliocentric and geocentric but the closer in planets are quite different.

As of right now June 1 2008; The geocentric moon the is15:28 Tau. The heliocentric Moon is11:48 Sag; Pluto 0:18 Cap geocentric; Pluto 29:43 Sag heliocentric.

Close planets like the Moon and Mercury are way off, the moon is almost the opposite side of the sky but the far out planets Neptune and Pluto are not that much off only 35 Minutes for Pluto.

Answer 4

The similarity between the meanings of these words is that they define a frame of reference.

Heliocentric (a Greek based word) refers to things relative to our Sun - for example the orbits of planets (Earth, Mars, Jupiter etc.) are helocentric as the planets orbit around the Sun.

Geocentric (another Greek based word) refers to things relative to the Earth - for example the orbits of the Moon and the International Space Station are geocentric as they orbit around the Earth.

Answer 5

They both are in the center. Geocentric means earth centered and helio-centric means sun-centered.

Answer 6

They both involve an object that is thought to be the center of a greater system. The Earth in the geo, and the sun in the helio.

Answer 7

The planets have always orbited in a perfect circle. Just like in both theories.

Answer 8

They both are seen to be, as observed from Earth's surface, equally possible to be Actual.

Answer 9

In both systems, the Moon goes around the Earth.

Answer 10

They both end in "ocentric".
