More planets are changing directions. First, Mercury circled retrograde. This week, Mars is reversing course and Neptune starts spinning forward again. Going retrograde and stationing direct are the ...

This summer, within our solar system, not one, not two, but a staggering seven planets will be in retrograde. While the term "retrograde" tends to conjure up feelings of dread and overwhelm among ...

Shedding light on the gravity of the situation. Most people do not realize that many of the stars and heavenly bodies they see in the sky no longer exist. In fact, many have ceased to exist for ...

Mercury will be in retrograde until Dec. 15, the last of four times it appears to move backward in the sky this year. For at least a portion of 2024, nearly every planet in our solar system has been ...

Lagrange points are spots in space where the gravity of multiple objects basically cancels each other out from the point of ...

An orrery is a moving model of a planetary system. Daniel Fabrycky, University of California at Santa Cruz, created two animated orrerys to display the 1,235 Kepler planet candidates. 1,235 Planet ...

Stargazers can now look up and see a planetary alignment in the night sky, or what some are calling a "planetary parade," throughout January. It's a dazzling cosmic event involving Venus, Mars, ...

A new analysis of Kepler data shows that one-third of small stars called M dwarfs may have the potential to host life. When you purchase through links on our site, we may earn an affiliate commission.

In this work, we extensively investigate the formation of near 4:2:1 mean motion resonances (MMRs) configuration by performing two sets of N-body simulations. We model the eccentricity damping, gas ...
