hydrogen, helium
gases in atmosphere 96% carbon dioxide, 3% nitrogen, 1% other mostly hydrogen and helium
number of moons
27

2
planet a is an
planet

Planet A is inner  

Planet A is Mars

Planet B is Outer

Planet B is Uranus

Solution:

We know that the inner planets are the planets which are close to the sun. They are relatively small, mostly rocky composition, and have few or no moons.

On other hand, the outer planets are the planets which are far away from the sun. They are mostly huge, ringed, gaseous and have several moons.

In the given problem,  

Planet A has rocky mantle and iron core, less no of Moons and no rings, also due to 96% of carbon dioxide, 3% nitrogen and 1% other gases this is denser, and Hence Planet A is inner planet. As the distance from the sun is 1.5 AU and no of moons are 2, hence Planet A is Mars.

On the other hand, Planet B is gaseous with hydrogen and helium gas, hence it is also denser and it has large no of moons and faint rings. So Planet B is Outer planet. As the distance of the planet is 19.22 AU and has 27 moons, hence Planet B is Uranus.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
