आकाशगंगा मे सौर मंडल का स्थान
हमारा सौर मंडल हमारी आकाशगंगा आकाशगंगा की एक भुजा में स्थित है, जो एक सर्पिल भुजा है।

हमारी आकाशगंगा में लगभग 200 अरब तारे हैं। लेकिन उनमें से अधिकतर तारे हम देख नहीं पाते। रात के आकाश में दिखाई देने वाली लगभग हर चीज़ हमारी आकाशगंगा में है।
हमारा सौर मंडल हमारी आकाशगंगा के केंद्र से लगभग 26,000 प्रकाश-वर्ष दूर मिल्की वे आकाशगंगा की परिक्रमा करता है, जिसका व्यास लगभग 1,00,000 (1 लाख) प्रकाश-वर्ष है।

दरअसल, सौर मंडल के केंद्र में स्थित सूर्य 270 किमी प्रति सेकंड की गति से अपने चारो ओर परिक्रमा कर रहे ग्रहों को अपनी ओर खींचता है। इस गति से यह 20 मिलियन वर्षों में आकाशगंगा का एक चक्कर पूरा करता है। अब तक हमारा सूर्य आकाशगंगा के 20 चक्कर पूरे कर चुका है।
चूँकि सूर्य आकाशगंगा मे 65 डिग्री झुका हुआ है, आप रात के आकाश मे आकाशगंगा देख सकते है।

Biography ka question

By Er. Alok Kumar
Shaktishali Foundation “There are a lot of things that go into creating success. I don't like to do just the things I like to do. I like to do things that cause the Shaktishali Foundation to succeed. I don't spend a lot of time doing my favorite activities. Have fun, work hard and money will come. Don’t waste time – grab your chances. Have a positive outlook on life. When it’s not fun, move on." Eralokkumar SHAKTISHALI FOUNDATION How It All Began I like to tell this story because it tells a bit about who we are and how it all started. My lovely and inspiring Mother, being the wonderfully organized person she is, set about answering every question in the book. She gave it back to me on my birthday in September, nearly two months later. I remember opening the book and seeing her answers to so many questions I never would have thought to ask her. I burst into tears (I've only done that one other time in my life) and realized that I was holding one of my most prized p...

Eralokkumar’s Presentation Information --------------------------------------------------------------------------------------- How to Remember Your Speech without Memorizing We all fear that moment when we speak to audiences. You look out on a sea of faces and your mind goes blank. You can't remember your next point and you wish you could disappear with your memory. You can avoid blanking out when you know how to maximize your mind. These tips will help you achieve total recall of your talk: Rehearse out loud. You'll remember more when you hear your own voice. Tape it and play it back. Listen to it in the car or as you fall asleep. 2. Practice the 3x5, 3x5 Rules. Avoid one lengthy rehearsal. Instead, take short chunks and practice them 3 to 5 times a day for 3 to 5 days. Frequency of repetition aids memory. 3. Create key words and phrases . The idea is to memorize concepts-not words.
