Transcript of Planets
A day on Venus lasts longer than a year It takes 243 Earth days to rotate once on
its axis. The planet’s orbit around the Sun takes 225 Earth days, compared to the Earth’s 365
Venus is the hottest planet in our solar system The average surface temperature is 462 °C, and because Venus does not tilt on its axis, there is no seasonal variation. Venus is the second planet from the Sun and is the second brightest object in the night sky after the Moon. Named after the Roman goddess of love and beauty, Venus is the second largest terrestrial planet and is sometimes referred to as the Earth’s sister planet due the their similar size and mass. The surface of the planet is obscured by an opaque layer of clouds made up of sulfuric acid. On June 5th, 2012, a transit of Venus occurred. This is when Venus passes between the Earth and the Sun. The next transit of Venus will happen in December 2117.
Radius: 6,052 km
Distance from Sun: 108,200,000 km
Gravity: 8.87 m/s²
Length of day: 116d 18h 0m earth days
Orbital period: 225 days
Density: 5.24 g/cm³
Earth is the biggest terrestrial planet. The earth's rotation is
gradually slowing at approximately 17 milliseconds per 100 years.
It would take 140 million years just for the earth to gain
1 hour to be 25 hours in a day. The earth has 1
moon, the earths surface earth was formed four and
a half billion years ago.Earth is the third planet from the sun
temperature is 88-58 Fahrenheit. The earth use to be centre
of the universe.
due to apparent movements of the sun
and planets in relation to their sight, ancient scientists insisted
that earth remained static, whilst other celestial bodies traveled
in circular orbits around it.Eventually,the sight that the sun
was at the center of the universe was postulated by copernicus, though. intresting facts
this is also not the case Polar diameter: 12,714 km
Orbit period:365.26 earth days
Orbit distance:149,598,262 km (1 AU)Equatorial circumference : 40,030 km. The earths mass is:5,972,190,000,000,000 billion kg
Mars is the fourth planet from the Sun and the second smallest planet in the Solar System. Mars is a terrestrial planet with a thin atmosphere. Mars has been around for about 4.5 billion years.The surface is made up of a thick layer of oxidized iron, dust and rocks of the same color. The dust that covers the surface of Mars is fine like talcum powder. Beneath the layer of dust on mars, the Martian crust consists mostly of volcanic basalt rock. Mars has a central core made up of metallic iron and nickel surrounded by a less dense, silicate mantle and crust. Like earth mars has moons to, accept mars has two moons called Phobos and Deimos.
-Mars has the tallest mountain in the solar system
- Mars and earth have the same landmass
-Mars has the largest dust storms in the universe
-Pieces of mars has fallen to earth
Jupiter is the 5th planet from the sun, and the largest planet in the universe. Jupiter’s surface area is 61,418,738,571 km’s and the radius is 69,911 km’s. The distance between the sun and Jupiter is 778,500,000 km’s, also jupiter has a diameter of 142,750 km’s. Jupiter is the first “gas planet”. The moons of jupiter are ( IO), (Europa), (Ganymede), and (Callisto). Jupiter is mostly made up of hydrogen and helium and has 50 moons and maybe 17 more so a total of 67 moons. If you look closley at jupiter than you might notice the Great Red Spot, and it is a gigantic storm (bigger than Earth) that has been raging for hundreds of years. Also the first person to discover and observe Jupiter’s moons was Galileo in (1564-1642). Interesting Facts
-All of the other planets could fit inside Jupiter, that’s how big Jupiter is.
-The mass of Jupiter is one-thousandths of the sun but its two and a half times of the whole solar system all together. (combined)
- Jupiter was named after The Roman Sky God, Zeus.
-On Jupiter it takes about 10 hours for jupiter to rotate or spin once. Jupiter makes a complete orbit around the sun ( it’s a year in Jovian time) so, 12 Earth years. (4,333 Earth days).
What is Neptune
Neptune is now the farthest planet from the sun after Pluto was claimed to be a dwarf planet in 2006. It has 13 known moons and it is the fourth largest planet by diameter and third largest by mass. It has a distance of 4,503,000,000 km from the sun and only one spaceship did fly by Neptune and discovered 4 complete but faint rings and six new moons in 1968 by the voyager2 spacecraft but before that Neptune was only known to have 7 moons. It was discovered in 1846 by Johann Gotfried Galle and 3 other people.
-its surface temperature is -201 °C
-Time Of A Full Day: 16h 6m
-It was named after the roman god Neptune
Saturn is the 6th closest planet to the sun and the 2nd largest planet in the solar system. The length of Saturn’s day is 10 hours 39 minutes on earth and it is 1, 433, 000, 000 kilometers away from the sun. Saturn has 53 moons in its orbit with 9 unofficial moons. Saturn is a planet of gas and is said to be made up of hydrogen and helium but scientists believe that the core of it is solid. The planet Saturn is named after the Roman god of agriculture. Saturn’s moon Titan is Saturn’s biggest moon and the 2nd biggest moon of the solar system. Saturn’s rings are made up of ice and rocks and there are 7 known rings. Saturn’s mass is 95 times bigger than Earth and is the last planet that can be seen without using a telescope or binoculars. Saturn is the flattest planet and is known as one of the “gas giants”. Saturn has a lot of wind storms and it takes 29 ½ days to do a full orbit around the sun. The rings of saturn were first seen in 1610 and is perhaps one of the most beautiful planets in our solar system.
1- Saturn has oval shaped storms, similar to Jupiter's
2- Saturn is the flattest planet
Where is it?:
Uranus is the seventh planet from the Sun and is the third largest in the solar system . It was discovered by William Herschel in 1781. It has an equatorial diameter of 51,800 kilometers (32,190 miles) and orbits the Sun once every 84.01 Earth years.
What is Uranus made of?:
Jupiter and Saturn are mostly made of hydrogen and helium, the ice planet, Uranus is much different. It is mostly composed of various ices, like water, ammonia and methane. The mass of Uranus is about 14.5 times the mass of the Earth.
1. Uranus has 13 rings
2. The surface temperature is -197º
4. Uranus is named after the ancient Greek deity of the sky
5. Uranus weighs 86,810,300,000,000,000 billion kg (14.536 x Earth)
Mercury is the smallest and closest to the Sun of the eight planets in the Solar System, with an orbital period of about 88 Earth days. Seen from Earth, it appears to move around its orbit in about 116 days, which is much faster than any other planet in the Solar system.It has no known natural satellites. The planet is named after the Roman deity Mercury, the messenger to the gods. Mercury is about 1.5 times as far from the Sun as it is at perihelion. Mercury's surface is heavily cratered and similar in appearance to the Moon, indicating that it has been geologically inactive for billions of years.Mercury is gravitationally locked and rotates in a way that is unique in the Solar System. As seen relative to the fixed stars, it rotates on its axis exactly three times for every two revolutions it makes around the Sun. As seen from the Sun, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two Mercurian years.
