Displayed on-screen, is some\ninformation about your target (Earth), your speed, and the current time\n(Universal Time, so it'll probably be a few hours off from your computer's\nclock).\n\nRight drag the mouse to orbit Earth and you might see the Moon and some\nfamiliar constellations.  Left dragging the mouse changes your orientation\nalso, but the camera rotates about its center instead of rotating around\nEarth.  Rolling the mouse wheel will change your distance to Earth--you can\nmove light years away, then roll the wheel in the opposite direction to get\nback to your starting location.  If your mouse lacks a wheel, you can use the\nHome and End keys instead.\n\nWhen running Celestia, you will usually have some object selected.  Currently,\nit's Earth, but it could also be a star, moon, spacecraft, galaxy, or some\nother object.  The simplest way to select an object is to click on it.  Try\nclicking on a star to select it.  The information about Earth is replaced with\nsome details about the star.  Press G (or use the Navigation menu), and you'll\nzoom through space toward the selected star.  If you press G again, you'll\napproach the star even closer.\n\nPress H to select our Sun, and then G to go back to our Sun.  Right click on\nthe sun to bring up a menu of planets and other objects in the solar system.\nAfter selecting a planet from the menu, hit G again to travel toward it.  Once\nthere, hold down the right mouse button and drag to orbit the planet.\n\nThe Tour Guide is a list of some of the more interesting objects you can visit\nin Celestia.  Select the Tour Guide option in the Navigation menu to display\nthe Tour Guide window.  Choose a destination from the list, click the Goto\nbutton, and you're off.\n\nThat covers the very basics.  For a more in-depth look at Celestia and the\ncontrols available to you, download the \"Celestia User's Guide\" (written by\nFrank Gregorio), available in several languages, from:\n  https://celestiaproject.space/guides.html\nThis web page also includes links to the Celestia README file translated into\nJapanese.\n\n\nMOUSE, KEYBOARD \u0026 JOYSTICK CONTROLS\n-----------------------------------\nSee the included file: controls.txt OR use the Help menu to display the Controls\nlist.\n\n\nSTAR \u0026 SOLAR SYSTEM BROWSER\n-------------------------------------------\nThe Navigation menu contains 'Solar System Browser' and 'Star Browser'\noptions.\n\nSTAR BROWSER\n\nBy default, the Star Browser window displays a table of the 100 nearest stars,\nalong with their Distance, Apparent and Absolute Magnitude, and Type. Clicking\non the column headers will sort the stars.  The table is not continuously\nupdated, so if you travel to another star, you should press the Refresh button\nto update the table for your current position.  The radio buttons beneath the\ntable let you switch between viewing a list of Nearest, Brightest, or 'With\nplanets' stars.  As with the solar system browser, clicking on any star name\nin the table will select it.  Use this feature along with the Center and Go\nTo buttons to tour the stars visible from any night sky in the galaxy.\n\nSOLAR SYSTEM BROWSER\n\nThe Solar System Browser displays a window with a tree view of all the objects\nin the nearest solar system (if there is one within a light year of your current\nposition.)  Clicking on the name of any object in the window will select it.\nYou can then use the Center or Go To buttons to display that object in the main\nCelestia window.\n\n\nSELECTING OBJECTS BY NAME\n-------------------------\nCelestia provides several ways to select an object by name...\n  1. Choose 'Select Object' from the Navigation menu, type in the object\n     name, and click OK.\n\n  2. Press Enter, type in the entire object name, and press Enter again.\n\n  3. Press Enter, type in the first few characters of the object name,\n     press the Tab key to move through the displayed listing until the\n     object is highlighted, then press Enter again.\n\nYou can use common names, Bayer designations or catalog numbers for stars.\nCelestia currently supports the HIP, HD and SAO catalogs. Catalog numbers must\nbe entered with a space between the prefix and the catalog number.\n\n\nKNOWN ISSUES\n------------\nFor up-to-the-minute answers to some common problems encountered when running\nCelestia, please view either the FAQ in the Help menu or take a look at the\n\"Celestia User's FAQ\" located on the Celestia User's Forum:\nhttps://celestiaproject.space/forum/\n\n\nUSER MODIFIABLE ELEMENTS\n------------------------\nYou can modify how Celestia starts up each time you run it, by defining your\nown start-up settings.  Simply open the file \"start.cel\" in a plain text\neditor and follow the in-file instructions.  Also, view the celestia.cfg file\nin a plain text editor to see additional settings.\n\nCelestia allows you to easily add real, hypothetical, or fictional objects\nby creating new catalog files. It is *not* recommended that you alter the\nbuilt-in data files; nearly all desired modifications and additions can be\nmade by placing new catalog files in Celestia's extras folders. There are three\ntypes of catalog files:\n - ssc (solar system catalog: planets, moons, spacecraft, etc.)\n - stc (star catalog)\n - dsc (deep sky catalog: galaxies, star clusters, and nebulae)\nAll three types of catalog file are text files that can be updated with your\nfavorite text editing program.\n\n\nCELESTIA RESOURCES\n------------------\nCelestia Web Site:\n  https://celestiaproject.space/\n\nCelestia User Forums:\n  https://celestiaproject.space/forum/\n\nSelden's List of Resources for Celestia:\n  https://www.classe.cornell.edu/~seb/celestia/\n\nCelestia Wikibook:\n  https://en.wikibooks.org/wiki/Celestia\n\nCelestia Motherlode:\n  http://www.celestiamotherlode.net/\n\nCelestia Source Repository:\n  https://github.com/CelestiaProject/Celestia\n\nCelestia Bug Tracking:\n  https://github.com/CelestiaProject/Celestia/issues\n\nCelestia Feature Requests:\n  https://github.com/CelestiaProject/Celestia/issues\n\nCelestia Subreddit:\n  https://www.reddit.com/r/Celestiasoftware/\n\nCelestia Archive Repository:\n  https://github.com/Anthony-B-Russo10/Celestia-Archive\n\nBUILDING FROM SOURCES\n---------------------\nSee file INSTALL for building instructions.\n\n\nCONTRIBUTIONS\n-------------\n\nAuthors\n-------\n  Chris Laurel        \u003cclaurel@gmail.com\u003e\n  Clint Weisbrod      \u003ccweisbrod@cogeco.ca\u003e\n  Fridger Schrempp    \u003ct00fri@mail.desy.de\u003e\n  Bob Ippolito        \u003cbob@redivi.com\u003e\n  Christophe Teyssier \u003cchris@teyssier.org\u003e\n  Hank Ramsey         \u003chramsey@users.sourceforge.net\u003e\n  Grant Hutchison     \u003cgrant.celestia@xemaps.com\u003e\n  Pat Suwalski        \u003cpat@suwalski.net\u003e\n  Toti\n  Da Woon Jung        \u003cdirkpitt2050@users.sf.net\u003e\n  Vincent Giangiulio  \u003cvince.gian@free.fr\u003e\n  Andrew Tribick\n  Hleb Valoshka\n  Li Linfeng\n\nContributors\n------------\n  Deon Ramsey ...........

Celestia wouldn't be the program it is today, without their help.\n\n\n\n\nThe Celestia Development Team\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FCelestiaProject%2FCelestia","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FCelestiaProject%2FCelestia","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FCelestiaProject%2FCelestia/lists"}
