Planetarium Moncayo

The students of Natural Science 1st Secondary invite you to travel along the Solar System in order to discover its wonderful planets and its star:

(Blanca Pérez)

Dear traveler, the Solar System consists of a central star, (the Sun) and the smaller celestial bodies: The eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, the moons that orbit those planets (there are 140 of them), and the millions of rocky asteroids and icy comets. All of these objects are held together in a group thanks to the Sun´s gravity.

(Inés Arqued and José Pablo Gallach) 

The sun is a huge sphere of gas at the centre of the Solar System. It is mostly made up of hydrogen and helium.
The Sun is so huge that more than a million planets the size of the Earth could fit in it. It makes up 99% of all the mass in the Solar System.
The sun spins on its axis and takes approximately 28 days to complete one rotation.

 (Oscar Asta and Juan Gálvez)

Mercury is the smallest and closest to the Sun of the eight planets in the Solar System, the orbital period is about 88 Earth days. It appears to move around its orbit in about 116 days which is much faster than any other planet.

It hasn't got any natural satellites. Its radius is 2240 km and its mass is 38% of the Earth's mass. The planet is named after the Roman deity Mercury. Its surface experiments the greatest temperature variation of all planets, ranging from -173ºC at night to 427 ºC

Venus is the second planet of the Solar System and its rotation movement takes 224,7 Earth days. It has no satellites. It has the same name as the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky.  Venus is a world of intense heat and volcanic activity.
(Lucía Herrera and Susana Laguna) 

The Earth is the third planet of the Solar System. The average distance between the Sun and our planet is 92,955,820 miles. Almost 70.8% of its surface is covered by water. It’s the largest of the terrestrial planets with an estimated mass of 5.9736 × 10^24 kg. 

The most remarkable aspect of the Earth is the presence of living beings.

(Carlos Montañés and Iván Lapiedra) 

Mars is the fourth planet from the Sun and it is the second smallest planet in the Solar System. It is often described as the "Red Planet" because of its reddish appearance. Mars is an inner planet with a structure very similar to the Earth's one.

Mars is the site of Olympus Mons, the second highest known mountain within the Solar System and of Valles Marineris, one of the largest canyons of the Solar System. Mars has two moons, Phobos and Deimos.

(Paula Garrido and Alejandro Brea) 

Jupiter is a giant gas planet. It is the fifth planet of the Solar System. It is placed between Mars and Saturn. Its   mass is 1,8987x1027 kg. It mass is 318 times greater than The Earth’s one and 3 times bigger than Saturn one. This planet is the biggest of the Solar System, its radius is 71.492,68 km.

It is made of hydrogen, helium, methane, water vapour, ammonia, ethane,   and  phosphine. Its minimum atmospherical   temperature is -163,15ºC ,its average atmospheric  temperature is -121,15ºC and its maximum atmospheric temperature is -75,15ºC.

Its rotation movement lasts 10 hours and Jupiter takes 12 years to orbit around the Sun.

(Sara Pinilla and Alba Julián) 

Saturn is the second planet in terms of size with a  radius of 58.232 km.
Its composition is: 94% hydrogen and 6 % helium as well as small amounts of ammonia and methane.

It has seven rings made of pieces of ice, dust and rocks.

It has got the slowest movent. It takes 29.457 years to complete its orbit.

(Álvaro Postigo and Lorena Sancho)

Uranus is the 7th planet in the Solar System, the 3rd largest and the 4th in terms of mass.

He has got many moons around it: Miranda, Oberón, Ariel, Titania, Umbriel, Punk…etc.

This planet is very similar to Neptune. The atmosphere is made of hydrogen and helium. Uranus is the coldest planet of the Solar System and consequently it is called the ice giant. The inner part of the planet is made of ice and rock.

(Alejandro Les and Victor Rubio) 

Neptune is the eighth and farthest planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Neptune has 17 times the mass of the Earth’s and is slightly more massive than Uranus, It has the same name as the Roman god of the sea.

(Carlos Tobajas)

Pluto is the second-most massive known dwarf planet after Eris. Pluto is composed primarly of rock and ice and it is relatively small. It was discovered in 1930.

In 2006, The International Astronomical Union (IAU) defined Pluto as a dwarf planet. 
Pluto has five moons: Charon, Nix, Hydra, Kerberos and Styx.
