One specific scenario, Dvali-Gabadadze-Porrati (DGP) gravity, gives rise to a potentially observable anomaly in the solar system: all planets would exhibit a common anomalous precession, dw/dt, in excess of the prediction of General Relativity. We......
This means that as a planet gets closer to its parent star, it speeds up; as the planet gets farther away, it slows back down. Kepler's third law: An object's orbital period squared is equal to the cube of its semi-major axis. This can be represented by the equation {eq}p^...
When checking astronomical tables for semi-major axes, try to find the value for the maximum distance between the object and the orbital center. Using the average or mean distance will only give you an approximation for the semi-major axis, based on the assumption of a circular (rather than ...
The time between conjunctions is the synodic period of the faster planet. When the faster planet has completed one revolution in time t, the other planet will have completed t/T fraction of one period. In order to catch up, the second planet will need to travel that same fraction of a ...
The orbital period of a planet is not directly measurable but it is obtained by the mean motion which is one of the many parameters which can be determined by fitting the observations in the standard ephemeris generation process. The DGP term could, then, be determined by including a correc...
Where k is is the proportionality constant. This is known as the law of periods. You could consider it the "period of a planet formula." The constant k is equal to 4π2/ GM, where G is the gravitation constant. M is the mass of the sun, but...
What about the Kuiper belt and the Oort cloud -- are they any different from the main one? Are there other asteroid belts in other solar systems like ours, or is the main belt unique? Keep reading to find out. Contents The Formation of the Solar System The Main Asteroid Belt ...
It turns out that there are many different things you can do with two pieces of glass, and these things can have a big effect on you when you use the lenses. As you will see in this article, there really is a difference between the various sunglasses you'll find out there. There ...
The Hubble Space Telescope is a reflector telescope that was sent into orbit around the earth in 1990. It is able to provide never before seen data because it is no longer affected by the earth's atmosphere.Answer and Explanation: The orbital period of the Hubble Space Telescope is around ...
How to Find a Hermit Crab. Although hermit crabs are sought after as pets, they can be fun to observe in their natural habitat. They might be difficult to find because of their camouflage and their tendency to run when disturbed. If you understand their
