The Neptunes

On both occasions, Galileo mistook Neptune for a fixed star when it appeared very close—in conjunction—to Jupiter in the night sky;[20] hence, he is not credited with Neptune's discovery. During the period of his first observation in December 1612, Neptune was stationary in the sky because it had just turned retrograde that very day. This apparent backward motion is created when the orbit of the Earth takes it past an outer planet. Since Neptune was only beginning its yearly retrograde cycle, the motion of the planet was far too slight to be detected with Galileo's small telescope.[21] In July 2009 University of Melbourne physicist David Jamieson announced new evidence suggesting that Galileo was at least aware that the star he had observed had moved relative to the fixed…

The eighth planet, Neptune, is surprisingly dynamic. With many thinking Uranus could be its twin, the real facts of Neptune are lost. Neptune has unique amount of moons, rings, temperature, gases, and also unique name. Neptune was discovered in the 1800s due to astronomers observing Uranus. Uranus’s placement wasn't exactly where they thought it was. They determined that there was another planet’s gravity pulling on Uranus. On September 23, 1846, the newly discovered planet was named after the…

Neptune is also known as the is a dark, cold, and windy planet that’s been discovered in 1846 by John Couch Adams, Johann Gottfried Galle, and Urbain Le Verrier. The reason for Neptune being -10 degrees is because it’s eight planets away from the sun. A way to describe Neptunes physical features is “Neptune has an incredibly thick atmosphere comprised of 74% hydrogen, 25% helium and approximately 1% methane. Its atmosphere also contains icy clouds and the fastest winds recorded in the solar…

windy? Well not only does Antarctica have such horrendous conditions, but the planet Neptune does as well! The name Neptune originates from the Roman god Neptune. Which means “The God of the Sea” in in Roman mythology, which is the equivalent of the Greek god Poseidon. Some people actually venerate these gods in a ceremony called Lectisternium, and offered food to gods and goddesses. Neptune is also the fourth biggest planet in our solar system. Its mass is about 1.0247e26 kg. The…

Neptune Neptune's core which is approximately the size of Earth is believed to be composed of rock and Ice the course covered with a thick mantle that contains water liquid ammonia and methane mixed with gases it is bitterly cold on Neptune with an average temperature of -210 degrees Celsius however it is warmer than expected for a planet's distance from the Sun since Neptune has an internal energy source like others Neptune is the fourth largest planet in terms of diameter making it the…

high internal temperatures and pressures. The core’s are about 10 times the size of Earth’s consisting of metals, rock, and hydrogen compounds. Jupiter, on the other hand is made almost entirely of hydrogen and helium 4. Because of its large size, Jupiter loses heat very slowly. The planet is still slowly contracting. Contraction converts gravitational energy into thermal energy. Neptune also uses contraction as a way of generating internal heat. Saturn, on the other hand, has liquid helium…

Jupiter is the largest planet, it’s volume is so large that it’s able to fit more than 1,000 earths.Because of Jupiter's large mass, it has 67 moons. All of its moons are denser than Jupiter because they are rocky like the terrestrial planets. Saturn is the second largest planet in the solar system, both in mass and density. Like most of the gas giants, Saturn is made of hydrogen and helium. Saturn has 62 moons, it has one of the largest moons in the solar system, Titan. It’s is even bigger than…

Saturn is a very cool planet it has rings around it that are little broke up pieces that are made of; small rocks, icy braked up bits, and some space junk. Saturn is also the sixth planet and it is not really far from the sun, Saturn also has sixty-two moons. Some planets have more than one or two moons some have none at all. They also call this planet a “Gas giant”. The other gas giants are Neptune, Uranus, and Jupiter are also gas giants. One of the moons named the “Cassini” accidentally went…

Figure 1 shows the location of the Kuiper Belt and some orbital properties of the Classical objects. At particular distances within the Kuiper Belt are the Resonant KBOs (RKBOs). They are given this name because their orbital periods are in resonance with Neptune (or at least very close) meaning that the number of times the object orbits the sun, and the number of times Neptune orbits the sun are tidy ratios such as 2:1, 3:2 and several others. Objects at a particular resonance all orbit at…

Fig. 11: Residuals in the osculating orbital elements of Nereid for long time interval. The semi-major axis is given in km, eccentricity in radians and the rest of elements are in degree (Saad & Kinoshita 2001). Vashkov’yak and Teslenko (2010) in addition to the effects of the mother planet Neptune, they considered the influence of the attraction of the internal satellite Triton on the evolution of the orbit of the external satellite Nereid. The disturbing function of Triton is…
