根据上文“A satellite is an object in space that orbits around another. It has two kinds—natural satellites and artificial satellites.(卫星是太空中围绕另一个物体运行的物体。它有两种——天然卫星和人造卫星。)”和下文“while artificial satellites are those made by man.(然而人造卫星是由人类制造的...
根据最后一段The closer to the earth,thestronger the gravity is.Therefore,these satellites must travel atabout 17,000 miles per hour to keep from falling back to the earth,while higher-orbiting satellites can travel more slowly.(离地球越近,引力就越强。因此,这些卫星必须以每小时17000英里左右的...
Besides, the part that carries the load and holds all the parts together is called the bus. Artificial satellites operate in a systematic way just like humans. Computers function as the satellite’s brain, which receive information, interpret it, and send messages back to the earth. Advanced ...
based on the tasks they need to perform.5, which can be 200-500 miles high. The closer to the earth, the stronger the gravity is. Therefore, these satellites must travel at about 17,000 miles per hour to keep themselves from falling back to the earth, while higher-orbiting satellites ca...
It was found to have come from beyond our solar system becauseits speed and path suggested it was not orbiting the sun or anything else. T he only other object confirmned to have come from another star system into our own is the come(彗星)21/Borisou ,discovered in 2019.Oumuamua looked ...
We, like many others, refer to all bodies orbiting in the KB as KBOs. Therefore, in effect, the KBO designator is merely an indication of the location of bodies orbiting there, rather than an indication of the kinds of bodies orbiting there. The term ‘trans-Neptunian object’ (TNO) also...
Just to start with, here is a version of the file with updated comments and names of symbols. endless_orbiting_loop_with_compensation.fla - Google Drive There were a couple of confusing ones in there - I apologise for this. Just the day before I had d...
Upon discovery, an object is given a preliminary designation consisting of a four-digit number indicating the year of discovery, a letter to indicate the half month of discovery, another letter to indicate the order of discovery within the half month, and another number to indicate the number ...
camera,is orbiting between the earth and the sun at a distance 2. 1 million miles. The camera on DSCOVR shot a(n) 3. (attract) view of the moon crossing in front of the earth. The image clearly shows the moon's far side 4. (light) up by the sun — tho...
it is difficult to model the evolution of the contour and prevent the contour from crossing over itself. The level set approach builds an original curve into a surface called a "level set function". Then, instead of moving the curve, the level set function expands, rises and falls. The ad...
