They orbit star X in circular orbits located in the same plane. Their tangent velocities is constant. Directions of orbiting of all planets is the same.Sometimes the event happens in this planetary system which is called Planet Parade. I

The one-month translation work was finally completed ...!! Thank you very much for your teammates (*^__^*)Anyway: This document is a Chinese application note for a series of astronomical python packages "ASTRO_PY_WHL (v1.1.1). pdf".We are based on github/foreign universities/python Library and other open source Python-astro library, will be briefly translated into easy-to-understand and professional literacy of the Chinese (Google translation is not too reliable!!) ), and in some important chapt

Http://poj.org/problem?Id=3101Approximate test instructions: The period of an object in a straight line that is not exactly the same as n a period of motion.This question I read the problem-solving report written, did not expect to choose to use the object, using the physical angular velocity or something.Since the cycles of n celestial bodies are known, their angular velocities are VI = 2*pi/ti, and if the No. 0 celestial body is chosen as the reference, then the relative velocity of the remain

I read an article two days ago saying that if the satellite orbit cycle is 90 minutes, How many times does the satellite circle around a day? (Observe from space, not from the ground, because the earth's rotation needs to be considered on the ground)

Chapter II Hellenistic--the study of Romacco2.1 Origins of Greek mathematical astronomyThe basic motive of Greek astronomy comes from the salvation phenomenon (which normalizes the chaotic phenomena)Eudoxus-Concentric ball model, a planet to do multiple uniform circular motions, superimposed into complex motion, concentric ball model not only solves the phenomenon of Plato's salvation, but also lays the basic pattern of Greek

_ novel reading network After several days of calm, I got up early in the morning and went back to the dormitory to see my boss surfing the Internet. Lin tianhao looked at it with a look. Dong Huang electric car agent said that nine stars will be connected this evening. The "nine-Star Ball" refers to the astronomical phenomenon with the sun as the center and the nine planets converge on the side of the sun, and its angle is less than 100 degrees. It takes 5900 to appear. "Hey, that's good. I wa

The dual-tube telescope is a useful astronomical observation tool. You can use it to watch a game, concert, or birds in the sky. You can also use it to enjoy the galaxy, the crater on the moon, several satellites around Jupiter and countless stars 2 million light years away. Many people mistakenly think that the dual-tube telescope is not used for astronomical observation. In fact, it is a favorite tool of many senior astronomical observers. For beginners, It is the entrance to astronomical obse

situation changes if the structures are illuminated from the side and viewed in front of as dark a background as possible. the structures then really seem to light up. Fine structures become visible: The spider webs (left) are barely recognizeable in front of the bright background-a light green field in this case. the picture completely changes when a dark background-a dark forest-is chosen. the structure seems to light up (right ). in both cases, th

Astronomy has a type of consecutive days of Confucianism (JD), which begins with the GMT noon of January 1, 4713 BC on 0th. There is also a simplified Confucianism Day (MJD): MJD = JD-2400000.5 MJD's 0th day started from GMT on November 17, 1858 AD.

, that is, sunrise and sunset, lack of full moon. A scientific definition is called the distribution, movement, location, state, structure, composition, nature, origin, and evolution of celestial bodies ". There is a specialized discipline that studies these phenomena, called astronomy. Of course, astronomy is so profound and far-fetched that if you are not interested, you do not have to go into it. Let's c

The beauty of mathematics 14: The importance of Mathematical Models Poster: Wu Jun, Google researcher [Note: readers who have been paying attention to the beauty of mathematics may have discovered that we are always looking for accurate mathematical models for any problem. To illustrate the importance of the model, I used a whole class in Google China in October. The following content is the abstract of my lecture.] In all astronomy homes, including

Astronomy experts said that the January 2 full moon suspended after the night sky, January 31 Our public will usher in the second month of the January night. If the weather is fine, the public will be able to enjoy the "blue Moon" astronomical landscape. Coincidentally, there is a total lunar eclipse that night, a "red moon" will also appear in the Sky Tim Romantic. The so-called "Blue moon" does not mean that people can see the blue-tuned moon with
