Explanation / Answer

1. Asteroid : (i) Irregularly shaped , 215m across , composed of metal.

Comet: (i) Irregularly shaped , 657m long ,mixture of ice and rock,highly elliptical orbit.

Planet: (i) Spherical, 0.0006AU across, made primarily of hydrogen and helium gas, with a rocky core has multiple moons.

Dwarf Planet: Spherical body with an icy crust, 500km across, orbits a larger body.

Moon: Volcanically active body, 3600km across, orbits a larger body.

2. Gas Gaints :

(i) Atmosphere of mainly hydogen and helium

(ii) Mantle of metalic hydrogen      

Ice Gaints :

(i) Atmosphere of mainly hydogen, helium and meth

(ii) Mantle of water, ammonia and methane ice  

Both

(i) Have a core made of rock or solid ice

(ii) have rings

3. Meteroid:

(i) A rock encounters earth's atmosphere but never reaches its surface

(ii) An object can be a piece of asteroid or comet.

Meteor:

(i) A rock doesnot burn up completely when in the earth's atmosphere.

(ii) A rock of 0.5m width crosses Earth's orbit.
