2. From the Internet, mathematical tools are available for roughly calculating orbits of the hundreds of objects discovered by amateurs and professionals.
3. It was a makeshift setup with numerous desks and phones installed in a large room near the computers used to calculate orbits.
4. However, based on Charon's calculated orbit, a series of mutual eclipses of Pluto and Charon was predicted and observed, confirming the discovery.
5. Although the comet's last passage occurred when Chinese astronomers were first recording celestial events, Marsden says reports from that time are not precise enough to calculate orbits.
6. It's difficult to find calculated orbit in a sentence. 用calculated orbit造句挺難的
7. In 2005, she was a teaching assistant at the Summer Science Program, which teaches astronomy to high school students using a curriculum based on observing and calculating orbits of asteroids.
8. General relativity is a more exact theory than Newton's laws for calculating orbits, and is sometimes necessary for greater accuracy or in high-gravity situations ( such as orbits close to the Sun ).
9. Spitaler, together with J . R . Hind, calculated orbits based on the observations, but despite predictions of a return in 1897, it was lost and remained so for the next few decades.
10. We have a rather technical article on astrodynamics which may be of interest to you, alternatively, look through the references and external links of said article for some more sources on calculating orbits.
11. The last theoretical prediction was then confirmed when 9 of the 10 satellites discovered by Voyager 2 were found in the predicted regions, with four on the pre-calculated orbits at less than 0.5 % error.
12. The masses of the primary and secondary determined from the calculated orbit are and respectively, but these depend strongly on the precise orbital inclination and both the masses are likely to be somewhere between and.
13. If so, the object receives a catalogue number and the observer of the first apparition with a calculated orbit is declared the discoverer, and granted the honor of naming the object subject to the approval of the International Astronomical Union.
14. The calculated orbit pinned down White-Ortiz-Bolelli as a member of the Kreutz Sungrazers, a group of comets which all originate from the fragmentation of one giant parent comet several hundred years ago, and which has provided some of the brightest comets ever seen.
15.

16. Pluto was later discovered at Flagstaff by Clyde Tombaugh in 1930, but in any case it is now known that Pluto's mass is far too small to have appreciable gravitational effects on Uranus or Neptune, and the anomalies are accounted for when today's much more accurate values of planetary masses are used in calculating orbits.
