Marking i will know if your wrong..

imagine you are an astronomer who recently discovered a new planet orbiting a distant star.
which set of characteristics would you use to classify this planet as an inner or terrestrial planet? check all that apply.

-dense and solid
-very large
-thick atmosphere containing hydrogen and helium
-lacking a solid surface
-located near a star

- dense and solid

- located near a star

Explanation:

Inner planets or terrestrial planets are considered to be smaller when compared to outer planets such as Jupiter, Saturn, Neptune and Uranus.

They are called terrestrial planets because they are characterized by having solid, rocky surface which is like desert and mountainous areas of the earth.

Example of inner planets aside planet Earth are:

1. Mercury

2. Venus

3. Mars

Inner planets are formed as a result of gravitational attraction which caused inner rings of material to accumulate and form massive rocks and heavy elements.

Also, astronomers speculate that, near the sun, are the heavier elements compacted. Elements such as iron and nickdel, whereas far away from the sun are elements such as methane, hydrogen and water condensed.

Therefore, to determine if a planet is inner and terrestrial it must have the following characteristics:

1. Rocky surface

2. Smaller in size

3. Located near a star.
