Help with random facts about planets in our solar system.?

We Answered:

You can probably find this in an encyclopedia or in a publication such as the World Almanac--or on Encarta if you have it.

Order of planets, from nearest to sun--Mercury, Venus, Terra (Earth), Mars, Jupiter, Saturn, Uranus and Neptune. Pluto is no longer considered a planet, but it would come next. In ascending order of mass, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn and Jupiter.

Neptune, Uranus, Saturn and Jupiter are gassy planets. Mercury, Venus, Earth and Mars are considered terrestrial--or earth-like--planets.

Andrew Said:

Anyone know about the solar system ?

We Answered:

Look up: Mercury, Venus, Earth, Mars, Uranus, Neptune, Jupiter and (Pluto, optional since it isn;t a planet any more)

Then look up Sun and Asteroids and even Comets.

Have fun.

SURVEY: What are the top 5 most interesting facts that you know about our solar system?

We Answered:

- The third planet from the Sun is unusually beautiful.
- The Sun is a variable star with a period of 11 years, but we don't know much about the mechanisms
- The Moon was formed by a giant collision. One of many that seemed to have occured in the early solar system, as we see the trace on all planets, except Jupiter.
- The moon Japetus has one hemispere with a much higher albedo than the other.
- The moon Europa is covered by an ocean of water under 5 km of ice.

Rita Said:

What do we know about planets outside our solar system?

We Answered:

I'm only a sophomore with a love for science and astronomy, all I know is that to detect a planet, years of observing the star for its light to fluctuate a little so show there is a planet there, as far as I know we only know of planets in our galaxy

A red giant is a luminous giant star of low or intermediate mass (roughly 0.5–10 solar masses) that is in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius immense and the surface temperature low, somewhere from 5,000 K and lower. The appearance of the red giant is from yellow orange to red, including the spectral types K and M, but also class S stars and most carbon stars.

The most common red giants are the so-called red giant branch stars (RGB stars) whose shells are still fusing hydrogen into helium, while the core is inactive helium. Another case of red giants are the asymptotic giant branch stars (AGB) that produces carbon from helium by the triple-alpha process.[1] To the AGB stars belong the carbon stars of type C-N and late C-R.

Prominent bright red giants in the night sky include Aldebaran (Alpha Tauri), Arcturus (Alpha Bootis), and Gamma Crucis (Gacrux), while the even larger Antares (Alpha Scorpii) and Betelgeuse (Alpha Orionis) are red supergiants.
