What form of energy is lost when a planet changes orbit?

AI Thread Summary
When a planet like Mars changes its orbit, it primarily exchanges potential energy for kinetic energy, especially when moving in an elliptical orbit. The energy remains constant overall, but any energy change typically occurs due to external factors, such as collisions with other celestial bodies. Unlike charged particles that lose energy through electromagnetic radiation, planets do not lose energy in this way during orbital changes. The discussion emphasizes that energy loss in planetary motion is contingent on the cause of the orbital change rather than being a self-initiated process. Understanding these dynamics is crucial for comprehending the mechanics of planetary motion.

In case Mars jumps from it's orbit to earth's,then will it lose it's energy
in electromagnetic radiation form or something else happens?
I found from Doc AL that only charged particle loses energy in electromagnetic form.Then in which form will it lose it?

In your scenario what made Mars jump?
 
lets not talk about 'mars jumping'.In a eliptical orbit,the planets have a different energy & when the planet moves from higher energy position to lower energy position,in which form does it lose it?Is it electromagnetic or something else?
 
In an elliptical orbit the satellite speeds up as it moves closer in, exchanging potential energy for kinetic energy.

u mean energy remains constant.
But if there is any energy change takes place,how will the planets lose it?
 
It depends on what causes the change to take place, such as a collision with another body. It doesn't take place by itself, in contrast with charged particles.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
