Solar System Orbits Ellipse

The Solar System formed 4. 6┬ábillion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system’s mass is in the Sun, with the majority of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials. The two largest, Jupiter and Saturn, are gas giants, being composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune, are ice giants, being composed mostly of substances with relatively high melting points compared with hydrogen and helium, called volatiles, such as water, ammonia and methane. All eight planets have almost circular orbits that lie within a nearly flat disc called the ecliptic.

The existence of ample amounts of hydrogen in the subsurface ocean of Enceladus indicates that microbes--if any exist there--could use it to obtain energy by mixing with carbon dioxide dissolved in water. This particular chemical reaction, termed methanogenesis, because it manufactures methane as a byproduct, may have been of critical importance in the emergence of life on our planet. What The Moon represents in You. In essence the Moon represents our emotions, responses, habits and contact needs. It symbolises the inner child that gains experience itself through the contact with others. It is our basic need to be loved and nurtured and the 'feeling' self looks to gain this from others. We usually receive this from our family and home environment and often a pet feeds our emotional self. Uncontrolled and immature emotions all come under the Moon's domain as we never lose our inner child. We often revert back into our Moon when we behave irrationally, or become moody or sulky, usually because our needs are not being met. If we feel unsafe or threatened we have a tendency to fall back on our Moon and it is by sign, house and aspect that describes how we react. Aside from the monthly phases of the moon, there is also a daily lunar effect on fish feeding habits. Moonrise and moonset appear to be very good times to go fishing, if other factors like the weather are cooperative. Studies show that fish are more active 90 minutes before and after either the moonrise or moonset. Given this, you now know when is a good time to go fishing, provided it fits your schedule!
