Use Kepler’s Third Law to find its orbital period from its semi-major axis. The Law states that the square of the period is equal to the cube of the semi-major axis 2=23 In order for the units to be correct, the semi-major axis should be in astronomical units, and the period sho...
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......

consider a giant planet have a 3/4 mass of it sun and with the distance of 50AU from the sun. That would make a binary star. It would rotate about a barycenter somewhere near the middle. pruthvi said: How it is possible in this case to say that the planet...
Polaris or the North Star is a star that appears almost directly above the Earth's rotational axis. As the Earth turns, every other star seems to spin around the axis, tracing out a circle in the sky, but the North Star appears to stand still. But no matter what time of night or wh...
3. The square of the period of a planet's orbit is proportional to its distance from the Sun cubed. When the units used for distance are Astronomical Units (AU) and time is measured in years, this relationship can be written explicitly as an equation relating the planet's period P and ...
A change in the Earth’s orbit, many scientists believe, transformed the “Green Sahara” into what is now the largest desert on the planet. While scientists are still trying to find out if the slow shift in orbit had rapid or gradual environmental conse
"What is extremely rare, though, is to find systems where the resonances span such a long chain of six planets." The unusual system was first discovered with NASA's Transiting Exoplanet Survey Satellite, better known as TESS, in 2020. Scientists followed up with observations on the European ...
In this article, we'll find out how galaxies were discovered and what types exist, what they're made of, their internal structures, how they form and evolve, how they're distributed across the universe, and how active galaxies might emit so much energy. Contents What Is a Galaxy...
Does the sun rotate? Why does the sun send out solar flares? Will the burn out? (And if so, when? And what will happen to Earth and its inhabitants when the sun dies?) Let's look at the parts of our nearest star, find out how it makes light and heat and explore its major feat...
