Is the United States the only country that has satellites in orbit around Earth?
Excuse me, but I was wondering if the United States holds a monopoly on having satellites orbiting the Earth? Are there other nations that have successfully launched and maintained their own satellites in space, or is the US truly the sole occupant of this realm? It would be fascinating to learn more about the global distribution of space-faring capabilities, if you could elaborate on this matter.
What is the lowest achievable orbit?
Could you please clarify for me, what exactly is meant by the term "lowest achievable orbit"? Are we referring to the closest distance a satellite or spacecraft can orbit around a celestial body like the Earth, without burning up or crashing into it? Is there a specific altitude or range that is considered the lower limit for stable orbit, taking into account factors such as atmospheric density, gravity, and orbital velocity? Additionally, is there a difference in the lowest achievable orbit for different types of celestial bodies, and how does it vary?
What is the blood supply to the orbit?
Could you please elaborate on the blood supply to the orbit? Specifically, what are the main arteries and veins that supply blood to this region, and how do they contribute to the overall health and functionality of the eye and surrounding tissues? Understanding the intricacies of the orbit's blood supply is crucial for medical professionals to effectively diagnose and treat various conditions affecting this vital area.
How far is orbit from Earth?
Could you elaborate on the concept of orbit and its relationship with Earth? Specifically, how does one measure the distance from Earth to an object orbiting around it? Are there any factors that affect the distance of an orbit, and if so, what are they? Furthermore, is there a standard unit of measurement commonly used in determining the distance of an orbit from Earth?
What is the weakest wall of orbit?
I'm curious, can you explain to me what is meant by the phrase "the weakest wall of orbit"? Is it a metaphorical reference to something within the cryptocurrency or finance realm? Or does it perhaps relate to a more literal, astronomical concept? Could you provide some context or examples to help me better understand what you're referring to and why it's considered significant?
