Not enough. What kind of nebula?

:phones:

 

the meaning of the word nebula originally meant "cloud", so in astronomy it got used as a term for galaxies, clusters and then there is the more conventional nebula (emmion and reflection) is that what you mean by type :cup:

 

Enceladus, has albedo of 99% :cup: its distance to Neptune is: 3.07billion km

:doh: Jay qu u still haven't got the question rightly,i haven't asked for the distance between encladus and neptune but the distance between planet of encladus and the neptune.

For the nebula question i think its' an emission nebula (a diffused one).:doh:

[Jay-qu]

err planet of enceladus is saturn, the distance between them is insignificant compared to the distance to neptune, if you want to get that nit-picky then you are going to have to specify the relative position of neptune and saturns orbits and where abouts enceladus is on its orbit.. etc.

[BrainForce]

Oh! my God .I AM JUST ASKING FOR DISTANCE BETWEEN SATURN AND NEPTUNE AND NOTHING ELSE.

Got it now,but its too late now. i will consider your answer as correct.

I know that it does change,but i wanted the mean distance.

[Jay-qu]

I was pretty sure I already gave you that.. but anyways..

Which itself varies with each passing moment...

 

You're no Alex Trebec, my friend.

[TheFaithfulStone]

You're no Alex Trebec, my friend.

 

I'm sorry, you didn't phrase that in the form of a question. The correct answer to "You are not like this person." Would have been "Who is Alex Trebec?" Again, "Who is Alex Trebec?"

 

JayQu, you now control the board.

 

You answer was "Albedo refers to this property of an object."

 

What is reflectivity?

 

The difference between a Type I and Type II supernova is this...

 

TFS

[InfiniteNow]

The difference between a Type I and Type II supernova is this...

One tends to be juvenile onset and categorized as genetic whereby the other tends to be adult onset and categorized as resulting from behavior?

 

Ba da bum... again.

 

 

Type 1 has shows no Hydrogen in it's spectrum, Type 2 does.

 

 

How long does light take to travel from the sun to Pluto when Pluto is closest to it (at perihelion)?

[cwes99_03]

Rougly, parahelion distance 30 AU. Light travels 1 AU in 8 minutes. Thus nearly 4 hours for light from the sun to reach Pluto.

 

What is the aphelion distance for Eris?

Who said anything about roughly? How long? :naughty:

 

 

PENDING CORRECT ANSWER TO ABOVE: What is the aphelion distance for Eris? <submitted by cwes>

I think the apehilion distance of eris is 97.6 AU.(i can't give answer in 10 decimal places)

Whoa there pumpkin seed. Back up for a moment. We are still waiting for an answer to the time it takes light to travel from the sun to pluto at perihelion...

 

:eek:

[cwes99_03]

How precise are you looking for Infinite? So far we have not mattered with exact precision as long as the information is correctly thought out and the proper calculations are made.

[cwes99_03]

What type of Nebula is Crab Nebula M1 ?Classify it further.

 

Specifically it is a Supernova remnant. It would thus be an emission type nebula. Is this enough or are you seeking further?

[InfiniteNow]

How precise are you looking for Infinite?

Hours, minutes, seconds...

 

 

How long does light take to travel from the sun to Pluto when Pluto is closest to it (at perihelion)?

[cwes99_03]

Well according to one website the distance at perihelion is 2,756,915,000 miles (29.6583407 AU)

At 185,000 mps, light would reach Pluto in 1409.24324 seconds or 248.370207 minutes, or 4.13951201 hours.

4hours 8 min 22.24324324324324324324 seconds

Well, I'll give it to you for effort... Here's what I came up with (~2 min, 10 sec different...plus, you are supposed to do these quizzes w/o aid of google or searches)... ;)

 

 

Distance at perihelion: 4,435,000,000 km

Speed of light: 299,792,458 m/s

 

Time it takes light to reach Pluto from Sun when pluto is closest:

 

14794 seconds, or...

246.57 minutes, or...

 

4 hours, 6 minutes, 34 seconds.

 

 

Now,

 

What is the aphelion distance for Eris?

97.56 AU, or 14,594,768,265 km ... as answered by BrainForce.
