'''अरुण अरुणग्रह''' सौर्यमण्डलको सूर्यबाट सातौं ग्रह हो। [[ग्याँस पिण्ड]] हो। यो [[सौर्यपरिवार]]मा तेश्रो ठूलो ग्रह हो। यसको २७वटा२७ वटा [[उपग्रह]]हरू छन्। जसमध्ये [[Miranda (moon)|Miranda]], [[Ariel (moon)|Ariel]], [[Umbriel (moon)|Umbriel]], [[Titania (moon)|Titania]] र [[Oberon (moon)|Oberon]] मुख्य पाँच उपग्रहहरू हुन्। यो ग्रह आफ्नो अक्षमा धेरै ढल्केको हुनाले ध्रुवीय दृष्टीकोणले तेर्सो परेको छ।
