29 - faster

35 - giant planets

36 - Jupiter

38  - Radiation pressure and solar wind

1 nucleus or core

2 helium [at the rate of approx 400 million TONs of hydrogen into helium every second.  This converts some matter into another element and some matter into energy.  This is the process in nature described by E-mc^2]

3 planets come from the protoplanetary disk of a system surrounding a newly formed star. 

4 light-year

5 Jupiter

6 meteorites

7 the Milky Way

8 Uranus -- it practically rolls around relative to the plane of its orbit

9 neap

10 Mercury, Venus, Earth, Mars

11 the Earth -- this is the Ptolomaic system

12 a middle aged star in its yellow phase

13 Mercury

14 first

15 Well, initial observations in the history of astronomy classifed it as a spiral galaxy, but modern technology and resulting observations have caused the general consensus to deem it a barred-spiral galaxy

16 right here on Earth

17 revolution

18 an irregular galaxy  -- theorized to be the result of a collision between two galaxies

20 galaxy

21 Not sure what you're asking for.  gravity caused the gas and dust to collapse in on itself until enough pressure caused enough heat to be generated for fusion to begin.  This caused the Sun to be born and begin shining.

22 No choices given.  The inner planets are the rocky or terrestrial ones :Mercury ,Venus, Earth and Mars. Jupiter, Saturn, Uranus and Neptune are gaseous and are the outer planets of our Solar System.

23 asteroids

24 solar eclipse

25 greater the gravitational pull

26 gravity

27 star

28 extreme global warming or the greenhouse effect

29 faster

30 terrestrial or rocky

31 coma

32 tides

33 elliptical

34 that would be us:  Earth

35 ??

36 Jupiter

37 Jupiter...but it has a LOT more than only 17 moons.  The volcanic moon is Io.  The one with a possible liquid ocean under its icy crust is Europa

38 dust and ice bits of its coma being blown by the solar wind

39 Moon  even though the Sun is a lot bigger and much much much more massive that the Moon, the Moon is closer and thus affects tides on Earth more.

40 meteors if they fly by or burn up [meteorites if they make it to the ground]

41 orbit around the Sun

Our sun is crazy sick! 400 million Tons of H converted every sec???!!!!! Craziness!
