2 Questions people always get wrong :)

[Benjamin]

I was just reading something from a few years ago and it said that 2 common questions a lot of people get wrong are:


How many stars are there in our solar system?

and


Can you name the 7 colours of the rainbow in order?


Know the answers?

(I do:tongue:)

[Stacey.]

I don't know the stars one, but the colours of the rainbow are: red, yellow, pink, green, orange, purple and blue. But I know some people put violet in there too.

[Vicky.]

Will you PLEASE stop creating threads and posting. its not allowed you know :bored:


:p

[Kazanne]

Stars is ONE

[Shaun]

In our solar system - 1, the Sun.
Rainbow colours in order, my guess would be: red, orange, yellow, green, blue, indigo, violet

[Lee.]

Richard of York gave battle in vain...

Thats how I remember the colours: red, orange, yellow, green, blue, indigo and violet

Not a clue about the stars though :)

[Kazanne]

Rainbow.

Red, Orange, Yellow, Green, Blue, Indigo, and
Violet.

[GiRTh]

ROYGBIV

Thas how I remember it.

[Benjamin]

Stars is ONE



:thumbs:

[Ramsay]

that stars question is shnakey

[Barbie]

Colours is easy

Red, Orange, Yellow, Green, Blue, Indigo, Violet.

Although here's a pointless fact. The person who split light only found 6 colours. But religion was very heavy back then and they refused to accept what he was saying because there wasn't 7 colours. In their view everything was in 7's, God made the world in 7 days and all that stuff. So he went back and pretended to find another colour (now known as indigo)

As for the stars my answer is, enough!

[Jordan.]

I didnt know either of them. :sad:

[Shasown]

There are more than 7 colours in a rainbow, its the human eye and brain that takes a central banding colour over a range of wavelengths.

Some people would actually visualise Cyan as opposed to true blue in the rainbow so it could be taken as Red Orange Yellow Green Cyan Indigo Violet.

Question 1: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune and Pluto*

(*Depends on whether you count it or not - officially its a dwarf planet and isn't counted)

Question 2: Red, Orange, Yellow, Green, Blue, Indigo, Violet. :spin:

The question was how many stars not planets. There is only one star, Sol - the sun.

[MTVN]

Knew the "how many stars" question, never really known the colours of the rainbow though.

[Twilight]

Theres only star - the sun, i thought most people knew that.....

[MTVN]

I guess people get it wrong by thinking of planets instead of stars.

[Stacey.]

What's the difference between planets and stars?

[Shaun]

Planets aren't about 2092938923 degrees hot :tongue:

[MTVN]

What's the difference between planets and stars?

Stars kinda create their own light and heat, and then planets orbit them and reflect its light.

[Shasown]

A star is a massive, luminous ball of plasma held together by gravity.

A planet (from Greek πλανήτης, alternative form of πλάνης "wanderer") is a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals.

didnt know either

i thought there was like hundres of stars.. well i see hundreds of stars anyway

Same! D:

[MTVN]

There are, but in our solar system the Sun is the only one. Outside of that there's billions.

There are billions of stars in the universe.

However there is only one star in our solar system - the sun.

Our solar system being the sun and the planets etc that orbit it.

[MeMyselfAndI]

so the solar system is the world?
but outside the world there a floating stars?
that we see from our world
..
:conf:

No, the solar system is just the 8 planets that orbit the Sun, so - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Then there's billions of other stars outside of this.

I was about to correct you and say 9 planets but they fired Pluto, he's now just a dwarf star :(

When I was a kid Pluto was a real planet :sad:

[Ninastar]

I miss pluto being a planet :'(

[Niall]

The question was how many stars not planets. There is only one star, Sol - the sun.

:shocked:

I must be a lot more tired than I think...I feel like such a douche. D:

[MTVN]

When I was a kid Pluto was a real planet :sad:

Yeah, poor little Pluto :( I do still think of it as a planet sometimes

[Stacey.]

I thought Pluto still was a planet?

[Niall]

I thought Pluto still was a planet?

Naa it was downgraded. I know this because I took astronomy. Fml.

[Tom]

according to the rainbow song its red and yellow and pink and green, orange and purple and bluuuuuuuuuuuuue

[Shasown]

I was about to correct you and say 9 planets but they fired Pluto, he's now just a dwarf star :(

When I was a kid Pluto was a real planet :sad:

Nope Pluto is a dwarf planet not a dwarf star, otherwise we would have a two star solar system

:shocked:

We all make mistakes, as the dalek said dismounting from a dustbin.(even questionmeisters -see above).

LOL I meant dwarf planet.

Somebody fetch me my dunce hat :)

Nah you dont need it, nobody's perfect. Except me!

I wasn't happy when they demoted Pluto, who suddenly makes that decision after all these decades and centuries.

[Tom]

and you can't say "my very easy method just speeds up naming planets" anymore and they've invented a new thing called a "dwarf planet" which Pluto now is along with 3 or 4 others

I wasn't happy when they demoted Pluto, who suddenly makes that decision after all these decades and centuries.

In the late 20th and early 21st century, many objects similar to Pluto were discovered in the outer Solar System, minor planet Chiron in 1976 disc object Eris in 2005, which is a lot larger than Pluto.

In 2006, the International Astronomical Union (IAU) defined what it means to be a "planet" within the Solar System. This definition excluded Pluto as a planet and added it as a member of the new category "dwarf planet" along with Eris Chiron and Ceres.

After the reclassification, Pluto was added to the list of minor planets and given the number 134340

Saying that there are some groups of astronomers, physicists etc who still regard Pluto as a major planet.
