Kuziva sezvisina kubhadhara sestarlight, kune yedu imwe yakabatanidzwa planet uye kune wese munhu anotarisa kumusoro kunzvimbo dzepasi rose kunze kwayo.
Pashure pekudzoka, tarisa kwauri. Uri kugara pachinhu chidiki, chakaomarara, chinofamba nesimba rakakura kupfuura simba rezwi uye chiri kudonha kwenguva yakareba pamusoro pechiedza chekare. Zvinhu zvakaita sesirivha muropa rako ne calcium mumapfupa ako zvakagadzirwa nezviratidzo zvakafa mushure mekunge zuva rizvarwa. Munguva pfupi isu tichaenda kunze, mune chaiyo scale, pasi penyika dzinotiratidza mwanga wedu. Muchidimbu, kufamba kwedu kunoitwa munguva yechiedza; ichi ndicho chinhu chakakosha. Tengani nhengo dzemuromo dzako kuti muone iyo yakajeka-yemavara ebhuruu dot. Iyi ndiyo chete nzvimbo yatinoziva uko munhu wese anenge akatarisa kusvika kudenga achifunga nezvezvimwe zvinhu.

Everything starts here. The Sun holds 99.86% of all the mass in the solar system: a fusion reactor 109 Earths wide.
Kubva kuzuva: 0 AU · Sunlight takes: 0 s · 5,499 °C
Panyika gore rimwe rinotora 88 zuva, asi kubva pazuva rimwe kusvika rinotevera zvinotora 176.
Kubva kuzuva: 0.4 AU · Sunlight takes: 3.2 min · One day lasts: 4,222.6 h · 167 °C
Asi kwete yakati wandei kubva kuzuva, asi yakaoma kwazvo. A runaway greenhouse inochengeta nzvimbo pa464 ° C, yakaoma zvakakwana kuti iome.
Kubva kuzuva: 0.7 AU · Sunlight takes: 6 min · One day lasts: 2,802 h · 464 °C
Iyo yakajeka-yekutema dot, uye iyo chete nzvimbo isu tinoziva kuti munhu wese ainge abvunza mibvunzo.Ini ndinofunga kuti chero dambudziko riti tiri kushanda pane rinogara pano.
Kubva kuzuva: 1 AU · Sunlight takes: 8.3 min · One day lasts: 24 h · 15 °C
Hapana munhu anofunga kuti pane imwe nyika ine hupenyu hwakafanana neyedu, asi vanhu vanofunga kuti hapana.
Kubva kuzuva: 1.5 AU · Sunlight takes: 12.7 min · One day lasts: 24.7 h · -65 °C
More than twice the mass of all the other planets combined. Its Great Red Spot is a storm wider than Earth.
Kubva kuzuva: 5.2 AU · Sunlight takes: 43.3 min · One day lasts: 9.9 h · -110 °C
Rings wider than 270,000 km and, in places, about ten metres thick. Saturn is less dense than water.
Kubva kuzuva: 9.5 AU · Sunlight takes: 1 h 19 min · One day lasts: 10.7 h · -140 °C
Kunyangwe ichifamba ne98 degrees, inogara iri panzvimbo yakafanana nezuva.Imwe neimwe yezvigaro izvi inowana makore 42 ezuva uyezve 42 ezuva.
Kubva kuzuva: 19.2 AU · Sunlight takes: 2 h 40 min · One day lasts: 17.2 h · -195 °C
Winds of up to 2,000 km/h, the fastest in the solar system. From here the Sun is only the brightest star in a black sky.
Kubva kuzuva: 30.1 AU · Sunlight takes: 4 h 10 min · One day lasts: 16.1 h · -200 °C
You have just crossed 4.5 billion kilometres. Sunlight makes the same journey in about four hours, and it has been making it for four and a half billion years.
Tarisa kuti sei ma orbits anoshandaSaka, kana iwe uchida kuziva kuti chii chinonzi physics yepasi, unogona kushanyira yedu peji rewebhu. Tine mapeji ewebhu anopfuura zviuru makumi maviri nemapfumbamwe uye isu tinopa ruzivo rwese rwaunoda nezve physics yepasi.

For all of human history, anyone could look up and find the Milky Way. Today one person in three never sees it, and eight in ten live under skies that are never truly dark. The cure is simple: shield the light, soften it, and let the night return when no one needs it.
