The Difference Between Inferior Planets and Superior Planets
Category : Hobbies, Games & Toys
Astronomers classify planets as "superior" or "inferior" depending on their distance from the sun in relation to Earth. Earth and other planets move around the sun in the same direction, in a circular motion. The famous astronomer Copernicus discovered the order in which the planets rotate around the sun and also the size of their orbits, using the concept of elongation. Copern

In What 3 Ways Are Jovian Planets Different From Terrestrial Planets?
Category : Education
There are eight known planets in our solar system (the International Astronomical Union downgraded tiny Pluto in 2006). These planets divide evenly into two categories: terrestrial and jovian. Mercury, Venus, Earth and Mars are terrestrial planets; Jupiter, Saturn, Uranus and Neptune are jovian. Terrestrial and jovian planets differ in size, composition and position relative to the sun. What is

Differences Between the Dwarf Planets & Planets
Category : Hobbies, Games & Toys
There was a controversy in 2006 when the International Astronomical Union (IAU) declared Pluto was no longer a planet and defined it along with the celestial bodies Eris and Ceres as "dwarf planets." There is only one distinct difference between regular planets and dwarf planets according to IAU. The other two definitions of a dwarf planet and planet are the same. Cleared an OrbitThe distinctio

Red Planets
Category : Hobbies, Games & Toys
So far, Mars is the only terrestrial body known as a "red planet." Considering the vast nature of space, it is safe to say that there may be similar planets in other areas of space. Mars is also unique because it was once believed to have supported life, although this has been confirmed to be untrue. Although many aspects of Mars and space itself remain an enigma, researching the red planet is pr

Which Planets Are the Gas Planets?
Category : Hobbies, Games & Toys
There are four planets in our solar system that are collectively known as the "gas giants," a term coined by the twentieth-century science fiction writer James Blish. They are also called "Jovians," as Jove is the Latin name for Jupiter, the largest of the four. The gas planets are made up almost entirely of gases, primarily hydrogen and helium. While they might have near-solid inner cores of molt

About the Sun & Planets
Category : Hobbies, Games & Toys
There are eight planets that orbit the central star in the solar system known as the Sun. These planets all revolve around the Sun in somewhat circular orbits and each orbit the Sun in the same plane, which is known as the ecliptic. The planets vary in size, distance from the Sun, and how long they need to complete one orbit of the Sun. SunThe dominant object in the solar system is the Sun, whi

What Planets Are Not Gas Planets?
Category : Education
Of our solar system's eight planets, the four that lie beyond the orbit of Mars are considered gas planets or gas giants. These planets, also called the Jovian planets, do not have rocky surfaces like the earth, but rather are made up mostly of hydrogen and helium. The Terrestrial planets, by contrast, have solid surfaces. They are made up of mostly silicate rocks and metals. Our solar system has

How to Map the Planets
Category : Education
Vast beauty and wonder exist in the exploration of our solar system's eight planets. All ages can deepen their experience and begin to explore the planets through mapping. Gauge a thorough understanding of the planets' proximity to one another, as well as the general layout of the solar system and its rotations. Facilitate discussion with this activity, promoting learning and knowledge using the c

Kepler's Third Law for All the Planets
Category : Education
Johanne Kepler, a German astronomist who worked under Tycho Brahe during the 1600s, devised a set of three laws that are used to describe the motion of planets in a system based around a central sun. While modern understandings of a solar system have changed since Kepler's time, the three laws are still considered accurate representations of the behavior of satellites when orbiting a central body.

Why Planets Eclipse
Category : Hobbies, Games & Toys
A solar eclipse is when a moon moves between the Sun and its planet, temporarily blackening the sun. Eclipses on Earth happen two to five times a year; most of these are partial eclipses. Total eclipses happen at the most once a year. Earth isn't the only planet experiencing eclipses; any planet that has a moon has some sort of eclipse. Lunar EclipsesA lunar eclipse happens when a planet moves
