    Orbit Space
AI Thread Summary
Objects in space orbit each other primarily due to their masses and the gravitational forces between them. The more massive body is closer to the center of mass, or barycenter, of the system, resulting in less noticeable motion compared to the less massive body. Both bodies exert gravitational pull on each other, leading to mutual orbits. Understanding this dynamic is crucial for studying celestial mechanics. The concept of the barycenter is essential in explaining these orbital relationships.

Is it because of their different masses?
 
Astronomy news on Phys.org
It's all about mass. Actually, both bodies orbit each other, just that the more massive body is closer to the center of mass of the system so its motion is less affected than the lesser mass body.
 
thanks :)
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
