Planet Jupiter

Planet Jupiter

Jupiter, the king of the planets, can be seen by the naked eye.

  • Jupiter is the fourth brightest ‘star/light’ in the sky and is made from gases and liquids.
  • Jupiter is named after the king of the Roman gods (Jupiter), due to the way it shines brightly and the way it moves among the stars.
  • Jupiter has more than 67 moons and counting.  The first four moons of Jupiter were discovered in 1610 by Italian astronomer, Galileo.
  • The first close-up photo of Jupiter was taken in 1973 by the space probe Pioneer 10.  The first rings were discovered by the space probe Voyager 1 in 1979 and are made from the dust of Jupiter’s inner moons.
  • Jupiter is averagely 778 330 000 km (483 340 000 miles) away from the sun.

  • On Jupiter, 1 day (rotation) takes 9.83 earth hours and 1 year (Jupiter’s orbit of the sun) takes 11.86 earth years, the orbit being an almost perfect circle.
  • Jupiter is the heaviest planet and weighs approximately 317.89 times of Earth’s mass and its diameter is 142 984 km (88 793 miles).
  • The colour of the clouds of Jupiter are orange, brown, red, cream and white.  The winds on Jupiter are caused from the heat of the sun and there is a storm raging on the planet called the Great Red Spot.
  • The magnetic field of Jupiter is ten times stronger than Earth’s field.
  • Jupiter gives off strange radio signals and produces lots of heat.

Light

Light

All light is bright and so are these ten facts!

  • Light comes in two forms of energy, brightness and heat. Light also has two groups, natural light, like stars and fires, and artificial lights, like electric bulbs and lamps.
  • The sun’s light travels 299,260 km/186,000 miles per second which means it takes 8 minutes to reach Earth.
  • A shadow forms when a ray of light shines on a solid object.
  • Transparent materials allow light to travel through it, while translucent materials let a little light through. Opaque materials let no light through.
  • When a ray of light touches a shiny or polished surface, the ray bounces back.

  • When light travels through a fine droplet of water or a prism, a rainbow forms.
  • Light rays contain colour. These colours are red, orange, yellow, green, blue, indigo and violet. Light’s primary colours are red, green and blue (RGB).
  •  Each wavelength of light is smaller than your hair.
  • The longest wavelength, red, has the least energy while the shortest wavelength, violet, has the most energy.
  • Light rays bounce off colours of its same colour type, while other light rays are absorbed when they touch a colour that is not its same colour type.
