Astronomy 1. how are the outer planets similar to each other? 2.how are the outer planets different from each other? 3.how are dwarf planets different from true planets? 4.what is the arrangement of the outer planets? what effect does their placement have the planets? 6.what is titan? why are scientists interested in it? (i usually don't use this site to ask questions because i usually know the answers but i don't have time to study before i need to submit this, you)

1. Outer planets are gaseous planets (Jovian Planets). All the outer planets have ring system. They have many number of natural satellites. They have longer period of revolution as compared to inner planets.

2. Outer planets are different from each other in the following way:

The size and mass of the four outer planets is different from each other. Uranus rotates in opposite direction as compared to rest of the planets. Jupiter is the largest planet where as Saturn is the lightest. All the outer planets have different composition of gases and water.

3. Dwarf planets are smaller in size and have irregular shape as compared to true planets. In our solar system, we have 8 true planets and 5 official dwarf planets but can be as many as 10,000 dwarf planets present in Kuiper belt.

4. The outer planets lie beyond asteroid belt in the following sequence: Jupiter, Saturn, Uranus and Neptune. Due to this arrangement, as the distance increases from the Sun, the temperature of the surface of these planets drops.

6. Titan is the largest moon of Saturn. Scientists are interested in studying Titan because of its dense atmosphere and liquid hydrocarbons lakes. Methane lakes are present on its surface. Although there is no water on it but scientists are exploring the possibility of life sustained on hydrocarbons as there is presence of pre-biotic environment with the possibility of biotic environment in sub-surface. It has methane cycle like water cycle on Earth and weather pattern.

scorpions are,

c.arachnids

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders
