CHARACTERISTICS

MERCURY

The earliest known recorded observations of

Mercury are from the Mul.Apin tablets.

These observations were most likely madeby anAssyrian astronomer around the 14thcentury BC.[93] The cuneiform name used to

designate Mercury on the Mul.Apin tablets istranscribed as Udu.Idim.Gu\u4.Ud ("the

 jumping planet").  

23

3.30x10

kg.

58 MILLION KM. 58 DAYS

&15 MINS.

87.97 DAYS Closest planet to the sun.Named after

the fleet footed messenger of the

gods.Airless,no significant atmosphere

to hold the heat.Smallest planet

covered with mountains,craters,ridges

& valleys.

VENUS Venus was known to ancient civilizationsboth as the "morning star" and as the"evening star", names that reflect the

early understanding that these were twoseparate objects. The Venus tablet of

Ammisaduqa, dated 1581 BC, shows that

the Babylonians understood that the twowere a single object, referred to in thetablet as the "bright queen of the sky,"

and could support this view with detailedobservations. 

108 MILLION KM. 243 DAYS

&24 MINS.

224.7 DAYS Same size as the earth,brightest object

in our sky besides the sun and the

moon.No satellites.Has thick

atmosphere made of carbon dioxideand sulfuric acid rain.

EARTH

Earth, of course, can be studied

without the aid of spacecraft.

Nevertheless it was not until

the twentieth century that we

had maps of the entire planet.

150 MILLION KM. 23 HRS.& 56 DAYS 365.27 DAYS The only planet that is

known to support

life.Has solid core of iron

surrounded by a field

that helps protect life.Ithas a single moon the

MOON.

MARS Johann HeinrichMädler and WilhelmBeer were the first"areographers". Theybegan by establishing thatmost of Mars’ surface

features were permanent,and more preciselydetermining the planet'srotation period. In 1840,Mädler combined ten yearsof observations and drewthe first map of Mars. 

228 MILLION KM. 24HRS. & 37 MINS. 686.98 DAYS Second smallest planet

in the solar system.It is

so called the red the

planet.Mars has almost

no atmosphere to help

trap the heat of the

sun.Mars has 2moons/satellites phobos

& deimos.

JUPITER The observation of Jupiterdates back tothe Babylonian

astronomers of the 7th or8th century BCE.[68] TheChinese historian of

astronomy, Xi Zezong, has

claimed that Gan De, a Chinese astronomer, made the discovery of one

of Jupiter's moons in 362

BCE with the unaided eye.

780 MILLION KM. 9 HRS. & 50 MINS. 11.86 YEARS

The biggest planet in

the solar system.The

fifth planet in order from

the sun.Jupiter is almost

entirely made up of 

hydrogen and

helium,with trace

amount of otherelements.One of the

brightest planets.Has

total of 16 moons.

SATURN

Saturn has been knownsince prehistoric times.Inancient times, it was themost distant of the five

known planets in the solarsystem (excluding Earth)and thus a major characterin variousmythologies. Babylonianastronomers systematicallyobserved and recorded themovements ofSaturn. In ancient Romanmythology, thegod Saturnus, from whichthe planet takes its name,was the god of the

agricultural and harvestsector. 

1.4 BILLION KM. 10 HRS. & 39 MINS. 29.46 YEARS The second largest

planet.Known for the its

many rings around it.It’s 

rings are made up of particles of ice ranging in

size.Saturn has much

less mass,and do it has a

low density.Has 21

satellites.

URANUS Uranus had beenobserved on manyoccasions before itsdiscovery as a planet, butit was generally mistakenfor a star. The earliestrecorded sighting was in

1690 when JohnFlamsteed. 

2.9 BILLION KM 17 HRS. & 14 MINS. 84 YEARS The third largest

planet.Composed mainly

of hydrogen and helium

gasses.Can sometimes be

seen by the naked eye.

NEPTUNE Galileo's drawingsshow that he firstobserved Neptune onDecember 28, 1612, andagain on January 27,1613. On bothoccasions, Galileomistook Neptune fora fixed star when itappeared very close—

in conjunction—to

Jupiter in the night sky. 

4.5 BILLION KM. 84 YEARS 17 HRS. & 14 MINS. It is very similar to

Uranus in size.Has a

weather system that is

very active.Some storms

with wind of 400 miles

per hour have lasted for

hundreds of years on its

surface.
