TRAPPIST-1 System 2D - v1.0.1
Project information
View settings :
- To move, keep the mouse pressed (selection click) and move it.
- To zoom in and out, use the scroll wheel.
- To center the (un)zoom on an object, select it and follow the same principle mentioned before.
- Two buttons can be used for fast (un)zooming, the one with a magnifying glass containing a plus symbol allows zooming in and the one with a magnifying glass containing a minus symbol allows zooming out. (
and 
)
- A cursor named “t” allows varying the value of the instant t.
- A boolean named “define time” opens an interface with which you can define a date that will vary the value of time t according to the input. It is enough to enter the values according to the seconds, minutes, hours, days and year then to click on the button
to confirm. It is possible to keep the values in memory with the boolean checked “keep values”. - To accelerate time, a text field under the name “Acceleration of time (in powers of 10)” allows you to accelerate or slow down the speed of time, it should be noted that the possible values must have a maximum of one decimal place and be contained in the interval from -1 to 10 and that also, this acceleration is done according to powers of 10.
- It is possible to stop and then restart the time with the “start time” Boolean.
- The boolean “show planet” allows displaying or not all the satellites.
- The boolean “real size objects” allows to display the real size of the planets (according to the average radius).
Miscellaneous features and disclaimers
- The unit of measurement of distance in AU (astronomical unit)
- The date defined in the project is an informative data on the evolution of the stars in relation to each other and does not follow the real model. That is to say, a star will have a certain position at such date in the project and that in reality this star did not necessarily have this position at the same date in the real world.
- Project created with the classic version of Geogebra 5.
- In case of problems with the system, click on the icon at the top left of the screen of the screen with two arrows to reload the activity.

System star information
The TRAPPIST-1 system is a planetary system located about 40 light-years away from Earth in the constellation Aquarius. It consists of a red dwarf star called TRAPPIST-1 and seven exoplanets that orbit around it. The exoplanets TRAPPIST-1b to TRAPPIST-1h were discovered in 2016 by the NASA Spitzer Space Telescope and the TRAPPIST observatory of the University of Liège. Further studies revealed that several of them are in the habitable zone of their host star, and have a mass similar to that of Earth, making them potentially suitable for life.
It is important to note that these values are estimations based on currently available information and may be subject to uncertainty and errors. Values may evolve with more precise observations and measurements in the future. These information was obtained from observations and measurements made by telescopes and observing instruments, and theoretical studies and simulations.
