नेपच्यून Neptune
नेपच्यून सौर मंडल का आठवां ग्रह है। इस ग्रह की खोज 4 अगस्त 1964 को हुई थी। इस ग्रह को दूरबीन से भी देखा जा सकता है।
नेपच्यून यूरेनस से एक अरब मील आगे है।
इस ग्रह की सूर्य से दूरी लगभग 4,498,252,900 किमी है। इसे अपने चारों ओर एक चक्कर पूरा करने में लगभग 19 दिन लगते हैं। अतः सूर्य के चारों ओर एक परिक्रमा पूरी करने में लगभग 165 वर्ष लगते हैं। इसका व्यास लगभग 49,528 किमी है।
अंतरिक्ष यान द्वारा भेजी गई जानकारी के मुताबिक यह इसी ग्रह के आसपास पाया गया है. लेकिन अन्य ग्रहों के छल्लों के विपरीत, यह गोलाकार नहीं है, बल्कि एक बिंदु पर खाली स्थान है। जिससे इसकी आवाज घोड़े की नाल जैसी होती है। यह किनारा दूरबीन से दिखाई नहीं देता।
नेपच्यून का आकार यूरेनस के समान ही है। सूर्य से बहुत दूर होने के कारण वहां अत्यधिक ठंड होती है। वहां का वातावरण जहरीली गैस मीथेन से बना है।
नेपच्यून के कुल 11 चंद्रमा हैं। साथ ही इस ग्रह के पास एक चुंबकीय क्षेत्र भी 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.
