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 given by: , (3.8) where is the product of the gravitational constant and mass of Triton, and refer to the radius vectors of Triton and Nereid respectively and . In spite of the fact that Nereid is classified as a distant satellite, the evolution of its orbit is presented as regular enough with practically secular variations of pericentric argument and node longitude, and with a conditionally periodic change of eccentricity and ecliptic inclinations. Perturbations from Triton are essentially smaller solar perturbations and are most noticeable during inclination change. The change of eccentricity is relatively insignificant and is about 0.02 for several thousand years. For other elements of the orbit, these perturbations are much less noticeable. 3.5. Gravitational effects on the planets’ orbits Planetary theory is originally, developed to be able to predict phenomena, and provide high accuracy ephemerides of the planets. The progression improvement has…

Core 1 Quantitative Assignment 1 Background: When wanting to find the mass of a massive object, the following is needed, Newton’s gravitational law (F = ma = mv2/r). Newton’s gravitational law can be used to calculate the mass which is represented by (M). This can be calculated if the velocity represented by (v), at orbital radius represented by (r), is known for the equation. When these two laws are put together they create the formula M = v2 r / G what G represents is the…

This paper will discuss the life of the German mathematician, astronomer, and astrologer Johannes Kepler. Who had a great impact in the 17th century scientific revolution, because of his development of the three laws of planetary motion. He is also remembered for the legacy he left that later provided one of the foundations for Isaac Newton's theory of universal gravitation. “Johannes Kepler was born on December 27, 1571 poor and sickly in what is now Germany. His father left home when Johannes…

Stress is a very complex topic. To my understanding it is an emotion felt not only mentally but physically as well. A large straining that you endure from being under immense pressure, at times you feel there is no way out. It can come from the negativity of your peers, and almost always from your very own self-doubt. Stress to me as a student and as a worker are very separate functions. From my student side I worry about not doing well on not only one but a series of demanding tasks from all of…
