Jupiter

=**Mohammad AL-Rowaily**= =**Orbital period**= To find Jupiter orbital period we need to use the equation of T^2=Kr^ since the radius of earth is 6378100 m and the radius of Jupiter is 71492000 m. You need to rearrange the equation to K= T^2=R^. Use 1 earth year as T (earth) and 1 earth orbit as R (earth). Use 5.2 earth orbits as R Jupiter. Put those numbers into T(earth)^2 / R(earth)^3=T(Jupiter)^2=R(Jupiter)^3 solve T for (Jupiter). The number that will show up is 11.86 there for every 11.86 year for earth, Jupiter will have 1 orbital period.

Ices ammonia water ammonium hydrosulfide(NH4SH) It is hard to know when Jupiter was discovered because it is one of the plants that we can see it from earth.NASA lists the planet as having been discovered by the Ancients. The planet is called Marduk in ancient Babylonian texts, Zeus in early Greek manuscripts, and Jupiter in Roman antiquity.
 * Data of discovery**
 * History**

Jupiter is 4.5 billion years old. The formation of Jupiter happen same as any other plant during the earliest parts of the solar nebula. A piece of dust covered ice that slowly accreted more material when the plant had accreted enough mass it developed a gravitational well allowing it to accrete even greater amounts of matter, including gases. It is believed that Jupiter should have been a star but something wrong happen that didn’t let it develop to be a star. Jupiter or Jove is the king of god and the go of sky and thunder it is known by the name Zeus in the Greek pantheon. Jupiter is a gas plant that produce a high amount of energy 1 thunder in Jupiter is 10000 times in earth. The Greek use to believe that Jupiter should be the king of gods or the god of sky and thunder because of the big size of the planet Jupiter sees a wide range of temperatures, from close to absolute zero at the outermost cloud layer to 36,000° Kelvin at the core. The high temperatures at the core are attributed to the extreme pressure of the planet bearing down at the center. At the inner layer of the clouds, temperatures can reach -145° C, while just above the core, where the planetary pressure has liquefied the hydrogen in the air, the temperature could reach 10,000° K. Resources Until now scientists didn’t find out any resources on Jupiter.
 * Mythology**
 * Atmospheric conditions**

There are lot things that we don’t know about Jupiter one of the mean things are how does Jupiter surface looks like. What will happen if we send a space props there. Are there any resources into Jupiter? Is it true that Jupiter was going to be a star? Will Jupiter crash into earth? All of these are things that we don’t know.
 * Significant and noteworthy Features**
 * The red spot on Jupiter is a storm that has been going for more than 300 years. This storm is 3 times bigger than earth.
 * Jupiter is a planet that has a very low density that if you put it on waters it will not sink.
 * Jupiter has many moons such as: Io, Lysithea, Aitne, Themisto, Amalthea.
 * Jupiter is the biggest plant on the solar system
 * Jupiter is one of the 5 plants that we can see it from earth
 * Jupiter is the most mention plant after earth
 * Jupiter is a gas plant
 * Features**
 * The read spot
 * Rings
 * Different color on surface
 * What don’t we know?**
 * Future plans or expenditures**

Until know NASA didn’t decide if Jupiter is one of the plant that we should study closely. Since NASA and other agency don’t have enough money to study those plant closely.
