To avoid collisions with man-made objects in Earth orbit, an altitude above low Earth orbit (LEO) is necessary. LEO typically ranges from about 100 to 1,200 miles, while geosynchronous orbits are around 26,000 miles. It is suggested that once an object is above LEO, the likelihood of encountering debris decreases significantly. Therefore, an altitude above LEO is recommended for minimizing collision risks. This discussion highlights the importance of altitude in ensuring collision-free orbits.

IN a relatively circular Earth orbit, how far away from Earth would you have to be in order to avoid collisions?
Ah. What do you know about the subject so far? What altitudes are used for the various low-Earth orbits? What altitude is used by geosynchronous satellites?

I should have been more explicit. Circular geosynchronous orbits, 26,000 miles as i understand it, is rarified as far as man made objects. I was wondering how far above Earth an object would have to be to have a high likelihood of not colliding with low Earth orbit objects and above.

almost missed it due to cloud, didnt see max at 0710 NZST as it went back into cloud.

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...
