Generally, planets closer to
the sun are rocky
(Mercy, Venus, Earth, Mars), whereas planets further away are made of gasses (Juptier, Venus, Uranus, Neptune) because as the planets formed, the planets closer to the sun had their gasses were stripped away due to the heat of the sun, whereas planets slightly further away …

What do you notice about the size of the planets?
The smaller, inner planets include Mercury, Venus, Earth, and Mars. The inner planets are
rocky
and have diameters of less than 13,000 kilometers. The outer planets include Jupiter, Saturn, Uranus, and Neptune. The outer planets are called gas giants and have a diameter of greater than 48,000 kilometers.
What are the main characteristics of the planets?
The characteristics of a planet are that it (a)
is in orbit around the sun
, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium [nearly round] shape, and (c) has cleared the neighborhood around its orbit.
What are the characteristics of a dwarf planet?
According to the International Astronomical Union, which sets definitions for planetary science, a dwarf planet is a celestial body that
-orbits the sun, has enough mass to assume a nearly round shape, has not cleared the neighborhood around its orbit and is not a moon
.
Which planet has the longest year?
As such, a year on
Neptune
is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).
Is Earth the only planet with life?
The third planet from the sun, Earth is the only place in the known universe confirmed to host life. With a radius of 3,959 miles, Earth is the fifth largest planet in our solar system, and it’s the only one known for sure to have liquid water on its surface. …
Earth is the only planet known to maintain life
.
Can humans live on any other planet?
Based on his Copernican principle, J. Richard Gott has estimated that the human race could survive for another 7.8 million years, but
it is not likely to ever colonize other planets
.
What is the hottest planet?
Venus
is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
What two planets have almost the same size?
Earth and Venus
are considered to be “sister planets”, they are roughly the same size and will get 5 and 4 pieces of the remaining clay.
