In this video, we use Python to calculate circular and geostationary orbits! Follow along as we apply physics equations to ...

Before we dive in, let’s do a quick review to appreciate what it actually means for an object to be in orbit. As Isaac Newton’s famous first law of motion states, an object in motion will stay in ...

The planets of our solar system move in ellipses. We've known this, so we are told, ever since Johannes Kepler devised his laws of planetary motion in the early 1600s. While it's true that orbits are ...

A novel type of multiple-apogee highly elliptical orbits termed as MAP HEO with a period of rotation between 14 h and 15 h is introduced. These orbits are designed to achieve continuous geostationary ...

UCLA astrophysicists have now measured the shape of the orbits of exoplanets—from the size of Jupiter down to the size of ...

SEVERAL attempts have been made in recent years to establish whether models of the galactic mass distribution admit a third isolating integral of motion for stellar orbits in addition to the ...

Ever since the 16th century when Nicolaus Copernicus demonstrated that the Earth revolved around in the Sun, scientists have worked tirelessly to understand the relationship in mathematical terms. If ...

Cometary orbits exhibit a wide range of shapes and eccentricities, not all being highly elliptical. Comets originating from the Oort Cloud possess highly eccentric elliptical orbits, subject to ...

Quick: How many moons does the Earth have? You might be forgiven for saying “one,” but it turns out the question isn’t all that easy to answer … because it depends on what you mean by “moon.” Of ...

Astronomers at The University of Texas at Austin's McDonald Observatory, along with colleagues at Caltech and elsewhere, have discovered a planet three times the mass of Jupiter that travels on a long ...
