From the street, I had a look of Jupiter in the East.
After a few minutes I got back inside. But this time instead of going to bed, I went upstairs at terrace to check out the sky.
My sister was scared to see me walking on the terrace at 2:30 AM and asked me what the hell I was doing there at that time. I told her that I am not feeling sleepy and kindly give me my binoculars. So she let me pick it up and do stargazing.
My binoculars were already focused so I just pointed it out at Jupiter. I don’t know why but I couldn’t see any of Jupiter’s moons. I just had a look at Jupiter. It was bright yellow shining object in binoculars.
Due to wind and my unstable hands, it was difficult to concentrate to find the moons so I just left it until next time.
Jupiter is the fifth planet from the Sun and the largest planet of the Solar system. 63 satellites of Jupiter have been discovered so far. It has a mass equal to 318 Earths.
Its so massive that if a person with a weight of 529.2 Newtons (its my weight) was on Jupiter, his weight at Jupiter would be 1338.66 Newtons. Isn’t it amazing?
After spending a little time with Jupiter, I turned my binoculars towards Epsilon Lyrae or the Double Double. With the help of Vega, I immediately found Double Double. It was so high that I couldn’t look at it more than 10 seconds. But I was easily able to resolve a double star out there.
I remember from my CATI Astronomy Night that I had observed Double Double with binoculars and with Obsession 18″ Telescope. I could easily see 4 stars with Obsession 18″.
Double Double is a quadruple star system in the Constellation of Lyra (The Harp) and is about 162 light years away from the Earth. When one looks at DD with naked eye, it appears as one, or under excellent sky conditions appears as two. But when it is observed through a telescope, it can be resolved into two double stars. That is why it is called Double Double.
At 2:45 AM, I thought its time to put the binoculars back. My goodluck that sister asked me to take laptop. I got the chance to write the report and do some surfing. Its 3:37 AM, all family is sleeping, my cat is playing with her kitten, night chowkidar is still whistling. And I am about to hit the “Publish” button.
All credit of this observing goes to the person who prepared such a strong doodh patti that made my sleep run away.
Good Night Folks.
Hope you learned the lesson: “Not to have tea late in night” 😀
Jokes apart, it was nice observations you made.
Lovely report. Liked the research you did about size, gravity and also loved the pictures. I had never seen the picture of resolved DD before. Wouldnt our weights be different at equator and poles of Jupiter? Also, I think it has no solid surface but all gas. Right?
Your sister is also interested in astronomy? Or is it bird watching? You found binos in her room.
I have seen people using binos while lying down and I do all my observation like that. Binos become very stable and I get longer sessions.
Actually Sir the gravity of Jupiter is 24.79 m/s^2 at the Equator and I used this number for calculating the weight of the person while he is standing at the equator of Jupiter. But the point worth mentioning is “One can never stand on the surface of Jupiter because its made up of gas” It has got no solid surface. I hide bino in her room so that my stupid cousin can not find and break its prisms 🙂 I had resolved many stars in the Beehive Cluster and at that time I was lying on a Chaarpai. But this time I was standing.

I like your blog Bilal, it’s very good 😉
I like your style of english which makes it more interesting to read and your observations are you make very well with images and comparisons. Well done! and keep it up! (but maybe keep off the Kadak Doodh Patii’s to get some sleep! lol)
Thank you István Sir, I love Kadak Doodh Patti ( Strong Tea with Milk ) 🙂
ah… I did wonder what it was. Me too!
That is half of the wonder with your page, there are lots of terms there I don’t understand which makes it much more interesting, rather than just talking about the observations you made 🙂
Bilal your writing is very enjoyable to read. I love your research also. Although some of the data you give I already know but it is refreshing to read it again.
Surely keep it up. I love kaddak doodh patti also. Even if it distroys my sleep :).
If your mass is Me on earth, your weight will be F=Me x 9.8 Newtons.
On jupiter your weight will be F = 54 x 24.79 = 1338.66 Newtons (not kgs).
On Earth you weigh F = 54 x 9.8 = 529.2 Newtons.
So by comparison, you weigh 1338.66/529.2 or 2.53 times more. You would feel like you had a mass of 136.6 kgs. You can manage that easily I think.
I may be wrong. Please confirm yourself.
Your mass will be same everywhere you go, Earth, Moon, Jupiter, anywhere.
Your weight will change due to grvitational force. You will feel light or heavy.
Your understanding of mass and weight are correct.
But your mass is 54kg. That is quantity of matter.
Your weight will be W=Mxg = 54*9.8 = roughly 540 Newtons on Earth’s surface where g=9.8 m/s^2.
Mass is usually not calculated. It is found by experiment, by standing on a weighing machine. It is called weighing machine but it finds mass and not weight. Dont get confused.
OK I got it,
Weighing machine shows us that mass of us is 54 KG..
W = M x G
W = 529.2 Newtons at Earth
M = 54 KG On Earth
W = M x G
W = 54 x 24.79
W = 1338.66 Newtons
Mass at Jupiter is same at 54 KG.
Now Got It right. Thanks for pointing out. The calculation I did in the post was correct but I had to write Newtons there.
Jupiter may be the largest planet in SS in size, but Earth is the largest planet…in population!!!…LOL
I remember when I was a child, someone had told me that when this world will run out of the provisions like water and food and place, all population will move to Jupiter. 🙂
How will one even stand there when it has got no surface.
What an idea bilal bhai 🙂
Sain very nice research but i must say you are a very good writer as well 🙂
Keep it up bro..
it is very much understandable.
actually all your observation is the magic KADAK DOODH PATTI .
Yeah on that day I slept after 5 AM in the morning….
