Description
New canon: forum.kerbalspaceprogram.com/iā¦
"Hatsune" (High Altitude Test Satellite Using Numerous Experiments) was the first satellite of the Hatsunia AeroSpace Development Agency, the space program of the United Federation of Hatsunia. It was launched by the four-stage Negi-1 solid-fuel rocket on 1967 August 31, the 60th anniversary of Hatsunia's foundation. The satellite had a mass of 42 kg and a length of 1.58 m (the empty fourth stage of the Negi-1 is counted as part of the satellite).
edit: changed the black portion because that's the solid fuel compartment, and it needed to be larger to hold more fuel
(I did some calculations and some guesstimation)

From your given dimensions, HATSUNE is about half the size and mass of Sputnik 1(whether or not the third stage is included).
Thus Negi-1 would have a payload capacity to LEO of at least 250 kg (half that of the Sputnik rocket).
Just thought I put out that useless calculation.

The Negi-1 is an all-solid rocket, and is based off Japan's L-4S (which could carry 26 kg to LEO). The payload capacity is probably just a bit higher than HATSUNE's mass.

So it has less thrust than my estimate?

The rocket payload capacity is independent from the payload mass, so just because HATSUNE weighs half as much as Sputnik, doesn't mean the launcher has half the payload capacity of the Sputnik rocket.

Now that I think about it,my calculations would only apply if you had created a rocket similar to the R-7 Semyorka.
My (horrible)mistake.

No need to worry.

Based on your earlier comment about the similarity between Negi-1 and the L-4S,you seemed to me to have implied that Negi -1 has roughly twice the thrust as the L-4S.
I hope this isn't another bad calculation. That would suck
I'm beginning to realize that trying to have a conversation like this may be horribly inefficient.
Not that I care that much.

Negi-1 uses the same fuels as the L-4S, but the stages are slightly bigger. The thrust is about the same as L-4S.

Loophole!!!
Negi-1 could not have the same thrust as L-4S.
L-4S could only send 26 kg into orbit.
HATSUNE is 42 kg.
Thus,if Negi-1 has roughly equivalent thrust,it could never launch HATSUNE into orbit!
Mwah ha ha!!
On a serious note,I'm getting confused about all this.

Thrust isn't necessarily directly proportional to payload capacity.

Thrust isn't the only factor in determining the capabilities of a launcher. There's also the masses of the stages and the type of fuel that is used for each stage.

longer version of sputnik ? 
her shape however reminds me a bit with Japanese's early Sattelite the "Osumi"

The design is a mixture of the Sputnik and Explorer 1 satellites. I decided to have a Explorer-1 type design so that the satellite would be long and skinny enough to be 1.58 meters long, like a certain turquoise-haired singer.
HASDA is indeed based off the Japanese space program, but it becomes much more advanced. For example, they develop indigenous manned spaceflight capability by 1984.
(The Senritsu-1 is like the L-4S, but with a higher lift capacity)

I decided to rename the rocket to Negi-1, just to let you know.

i expect there would be next rocket or sattelite named as "Asuna"

No, it's not a reference to that. (I don't watch anime, anyways)
It's a reference to that vegetable associated with Miku (negi, or green onion; sometimes called a leek, but that's different from a green onion)
