Ilanga
Ilanga lethu: ibhola le-plasma eshushu eligcina cishe u-99.86% wesisindo se-solar system.
NASA
Isibhakabhaka sethu: isizinda sokuba khona kwamandla wonke emhlabeni, kanye ne-ancre egcina yonke iplanethi ku-orbit yayo.
Ilanga liyisinkanyezi esiyi-G-type main-sequence (i-spectral type G2 V) esingama-4.6 billion years old. Ikhanya ngokuxhuma i-hydrogen ibe yi-helium engxenyeni yayo, lapho izinga lokushisa liyi-15.7 million kelvin. I-photosphere, indawo ebonakalayo, inezinga lokushisa elisebenzayo le-5772 K.
Ayikho ejikeleza njengengxenye eqinile: i-equator yayo ijikeleza kabili ngezinsuku ezingu-25 futhi ama-pole ayo ngamahora angama-35. Zonke iziplanethi, iplanethi encane, ama-asteroid kanye ne-comet kuhlelo lwelanga ziyijikelezisa.
Amasu
Amathuluzi nama-lessons asebenzisa amamodeli alula ukufundela kuphela. Akufanele asetshenziswa ukuhlola, ukuhlela umsebenzi noma noma yiluphi ukhetho lokusebenzela. Izitifiketi zimahhala futhi aziqinisekisiwe. Funda isichazamazwi sezinto ezifundiswayo
