1. The intensity of heating culminates at perihelion, when dust devils become very numerous.

2. Thus, at consecutive perihelion passages, opposite points on the equator pointed at the Sun.

3. How much does the direction of perihelion change each orbit?

4. So, the perihelion cannot be considered as a verification of Einstein's theory although it does suggest that his theory would be in the right direction.

4. try its best to gather and create good sentences.

5. W hen the Earth moves from perihelion to aphelion, its radiation belts are expansion, and aphelion to perihelion contraction.

6. If capital M were the Sun, we would call that "aphelion" and "perihelion."

7. According to Marsden's calculations, this comet reaches its closest point to the Sun (perihelion) on March 18th.

8. When perigee and perihelion coincide tidal range is at its greatest.

9. This resonant condition permitted Mariner 10 to fly by Mercury at close range at the times of alternate perihelion passages.

10. As long as a comet nucleus is still active, fresh clouds of dust are emitted at each perihelion passage.

11. The point in the orbit nearest the sun is called perihelion, while the point farthest is called aphelion.

12. Still, by January 11 sun-staring spacecraft SOHO should be able to offer web-based views as the comet heads toward a perihelion passage inside the orbit of Mercury.

13. This paper derives in detail the gravitational field of the sun by using the Schwarzschild metric, and expounds the advance of the Mercury's perihelion with the general theory of relativity.

14. Easy to spot in binoculars for now[], McNaught will sink into the twilight along the eastern horizon in the coming days as it heads toward perihelion (closest approach to the Sun) on July 2.

15. The splendor of Aquarius meteor shower currently seen across the night sky is the ice particle dust sprayed out by Halley's Comet during last perihelion pass.

16. In all this Cuban business there is one man stands out on the horizon of my memory like Mars at perihelion .

17. The Q is - do you mean Pluto in its aphelion or perihelion ?

18. Halley's Comet with average run cycle 76.01 years passed through perihelion last time in 1986, the next will appear in 2061.

19. This composite neatly compares two pictures of the Sun taken with the same telescope and camera on the dates of Perihelion (closest approach) and Aphelion in 2008.

20. This means that the Earth moves faster along the orbit in winter near perihelion .

21. The angular deviation, as observed from the sun, of a planet from its perihelion.

22. He also figured out the planet goes faster when it's at perihelion, nearer the sun, than when it's at aphelion, its farthest distance.

23. This happens around the time that Mercury arrives at that part of its orbit which places it closest to the Sun (called perihelion ), where it's orbital speed can briefly exceed its rotational speed.

24. But surprising Comet McNaught - whose January 12 closest approach to the Sun ( perihelion passage) was well inside the orbit of Mercury - gave an enjoyable performance in bright blue daytime skies.

25. The anomalistic year is the time between successive transits of the Earth through the perihelion.
