They are generally colder.
one of the most common metals.
Organisms in the same species have the most characteristics in common, as they are capable of interbreeding and producing fertile offspring.
Most planets have elliptical orbits around the Sun. These orbits are slightly elongated circles, with the planet closer to the Sun at one end (perihelion) and farther away at the other end (aphelion).
The composition of the Solar Nebula, with materials such as gases, dust, and ice, largely determined the characteristics of the planets. These materials and their location within the nebula influenced factors like temperature, pressure, and density, which in turn affected the formation and composition of the planets.
Most Planets seem spherical, but have lots of indentations. There are no common factors among planets and all appear to have physical differences
Both Jovian planets and Terrestrial planets share a similar amount of characteristics. For example, Jovian planets are gaseous, large and farthest from the sun. While Terrestrial planets are rocky, dense, closest to the sun and small (in comparison to Jovian planets). The two planets with the most similarities are Venus and Earth hence them being called "sister planets" due to to their similar masses.
Atoms, DNA strand, Planets The most common is the Lithium atom.

Of the major planets, Neptune. The speed of planets in their orbits is directly related to their distance from the sun. The farther a planet is from the Sun, the slower its orbital speed.
Water in some form has been discovered on most if not all the solar planets. This is not terribly surprising, since water is composed of the two most common reactive elements in the universe. (Helium is more common than oxygen, but it is not reactive.)
There is no Planet Kepler. The Kepler telescope was built to find planets in other solar systems. Planets it finds are given designations such as Kepler-62e. The telescope has found hundreds of planets with a wide range of characteristics.
