Physical properties of objects that orbit each other in the universe

AI Thread Summary
Objects that orbit each other can have their physical properties determined through measurements of mass, which influences orbital speed. The orientation of orbits relative to Earth allows for the assessment of additional properties such as radius, luminosity, temperature, and limb darkening. These measurements can also provide insights into the composition of any surrounding atmospheres. Understanding these properties is crucial for studying celestial mechanics and the characteristics of astronomical bodies. Accurate measurements can reveal significant information about the dynamics and nature of orbiting objects in the universe.

A question from my asronomy class...

Given that we are able to measure positions, velocities and timescales of objects in our universe, what sort of physical properties can we determine for objects that orbit each other in the universe?

I have tried reading through my textbook for ideas and have come up with nothing... any ideas would be greatly appreciated!

Thanks!

We can measure mass. The more massive, the quicker they orbit.
 
Depending on how the orbits are oriented, wrt us here on Earth, lots of other physical properties become amenable to measurement (albeit, with caveats). For example: radius (of each object), luminosity (ditto), temperature (ditto), limb darkening (ditto), composition of any extended atmosphere, ...
 
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 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
