Click on the "Calculate" button. Notice that the distances and sizes of the planets will automatically fill in. I've also provided some other interesting scale comparisons at the bottom of the chart. You can now build your scale model. You can do this with a long tape measure, or you can measure the size of your pace and walk it off counting the number of steps you take. For instance, make the sun's ball the largest. One way to determine ball sizes is to imagine if the Sun was a beach ball.
Mercury, Venus, Earth, Mars and Pluto would be the size of a pea. Jupiter would be softball-sized, Saturn the size of a baseball. Uranus and Neptune would be the size of a golf ball. Paint the planets. Don't forget to paint rings on Saturn. Allow the planets to dry. Cut a inch circle out of the cardboard box using the scissors. Find the center of the cardboard and make a black dot using the marker. Draw out orbit paths on the top of the cardboard using a compass for perfect circles. Greenhouse — temperature of the greenhouse effect in Kelvins.
Bright — rendering brightness. Default value is Opacity — rendering opacity. To avoid visual artifacts, use the default value of 1. Default value is 3. Hue — change of the color hue. Default value is 0. Saturation — change of the color saturation. Default value is 1. Composition — the tag describing the chemical composition of the atmosphere. The tag must contain several numerical parameters named after gases; values are the amount of these gases in percent.
Example of the Composition tag for Earth:. All values except Composition can be changed in real time with the Planet editor. If the Atmosphere tag is not specified, the atmosphere may be generated procedurally. If you want to disable the procedural generation, use this parameter in the Planet tag: NoAtmosphere true. This is the aurora tag. For physical realism, do not create aurora on airless bodies.
Aurora is always created at the top of the atmosphere, this means that its bottom height is equal to the height of the atmosphere. Height — the vertical span of the aurora in km. TopColor — aurora top color RGB. BottomColor — aurora bottom color RGB. NorthLat, SouthLat — latitude of the center of the auroral ring in degrees. NorthLon, SouthLon — longitude of the center of the auroral ring in degrees. NorthRadius, SouthRadius — radius of the auroral ring in km.
NorthWidth, SouthWidth — width of the auroral ring in km. NorthBright, SouthBright — brightness of the auroral ring. NorthParticles, SouthParticles — number of particles sprites in the auroral ring. The default vale of is used if not specified.
If the Aurora tag is not specified, the aurora may be generated procedurally. If you want to disable the procedural generation, use this parameter in the Planet tag: NoAurora true.
Texture — the path to the rings texture. The first row of pixels is a front-light radial color pattern with opacity in the alpha channel , and the second row is a back-light radial color pattern with opacity in alpha channel. If the Texture parameter is not specified, a procedural texture will be generated.
InnerRadius — radius of the inner edge of the rings in km. OuterRadius — radius of the outer edge of the rings in km. FrontBright — brightness of rings when front-lit. BackBright — brightness of rings when back-lit. Density — global opacity multiplier. Brightness or Exposure — global brightness multiplier. RotationPeriod — rings rotation period in hours.
Does not affect anything because ring textures in the current version 0. If the Rings tag is not specified, the rings may be generated procedurally. If you want to disable the procedural generation, use this parameter in the Planet tag: NoRings true. This is the accretion disk tag. Used to create an accretion disk around a black hole, neutron star, or white dwarf.
InnerRadius — radius of the inner edge of the disk in AU. If not specified, a procedural value is generated. OuterRadius or Radius — radius of the outer edge of the disk in AU. AccretionRate — accretion rate in solar masses per year. Used to calculate other parameters if they are not specified.
Temperature — temperature of the hottest part of the disk in Kelvin. Luminosity — luminosity of the disk in Solar luminosities. TwistMagn — strength of the twist effect on the texture. Density — density or opacity value. If the AccretionDisk tag is not specified, the accretion disk may be generated procedurally for black holes, neutron stars, and white dwarfs. If you want to disable the procedural generation, use this parameter in the Planet tag: NoAccretionDisk true.
MaxLength — maximum length of the tail i. Particles — number of particles sprites. GasToDust — gas particles to dust particles ratio. Value of 0. Bright — overall brightness of the tail. GasBright — brightness of the gas particles. DustBright — brightness of the dust particles. GasColor — color of the gas particles.
DustColor — color of the dust particles. If the CometTail tag is not specified, the comet tail may be generated procedurally. If you want to disable the procedural generation, use this parameter in the Planet tag: NoCometTail true. This is the star corona tag. Used only for normal stars i. However, those emissions can be used to create "false" sounds that is, not the real "sound" a planet or other object might make. As one example, people have captured emissions given off when charged particles from the Sun encounter our planet's magnetic field.
The signals are at really high frequencies that our ears can't perceive. But, the signals can be slowed down enough to allow us to hear them.
They sound eerie and weird, but those whistlers and cracks and pops and hums are just some of the many "songs" of Earth. Or, to be more specific, from Earth's magnetic field. In the s, NASA explored the idea that emissions from other planets could be captured and processed so people could hear them.
The resulting "music" is a collection of eerie, spooky sounds. These are literally artificial depictions of real events. It's very similar to making a recording of a cat meowing, for example, and slowing it down to hear all the variations in the cat's voice.
Not exactly. The planets don't sing pretty music when spaceships fly by. But, they do give off all those emissions that Voyager, New Horizons , Cassini , Galileo, and other probes can sample, gather, and transmit back to Earth.
Venus is a pale The Mystics - Thats The Kind Of Love (Vinyl). To mark a planet's place you can use a piece of paper on a post that you stick into the ground, or you can use a flag, or even a person. If the AccretionDisk tag is not specified, the accretion disk may be generated procedurally for black holes, World Three - Squarepusher X Z-Machines - Music For Robots (File) stars, and Planets What You Make It dwarfs. Age — age of the object in billions of years gigayears.
