Seekho
Daada-daadi ke gaon mein saaf raat ko Zoya hazaaron taare dekhti hai, shehar se kahin zyada. Daada kehte hain har ek suraj hai: gas ka bahut bada, garam, chamakta gola. Wo chhote bindu isliye dikhte hain kyunki bahut-bahut door hain.
Hamara Suraj bhi ek taara hai, hamare sabse paas wala. Isiliye itna bada aur chamkeela dikhta aur din ki roshni deta hai. Agla sabse paas ka taara itna door hai ki uski roshni humtak pahunchne mein chaar saal se zyada lagte hain!
Bahut pehle log chamakte taaron ko jodkar shapes ki kalpana karte aur naam dete the. Aise taaron ka samooh taaramandal (constellation) hai. Saptarishi saat chamakte taaron ki karchhi jaisa dikhta hai; Orion (Mriga) shikaari jaisa jiski kamar par teen taaron ki seedhi patti hai.
Taaramandal ke taare asal mein paas-paas nahi hote; sirf Dharti se paas dikhte hain. Taaramandal aasmaan dekhne waalon ko raasta dhoondhne mein madad karte hain, map ke nishaanon ki tarah.
Explore: taare jodo.
- Saat taare jodkar Saptarishi banao (karchhi: katori aur handle).
- Ab Orion banao: kandhe, teen taaron ki kamar, aur pair.
Yaad rakho
- Taare chamakti gas ke bade garam gole hain; Suraj sabse paas ka taara hai.
- Taaramandal pattern banaata taaron ka samooh hai, jaise Saptarishi aur Orion.

Socho
Gaon mein shehar se kahin zyada taare kyun dikhte hain?
Ek answer
Shehar ki roshni aasmaan ko ujla kar deti hai (light pollution), jisse dhundhle taare chhup jaate hain. Gaon ke andhere aasmaan mein dhundhle taare bhi dikhte hain.
