Planets

In which space?

Your sentence should be, "how many planets are there in space? Or how many planets are there?"

When talking about space meaning outside earth then there isn't an article. The space is used to decribe an area. The space under the stairs. The space in the garage, etc.

Anonymoushow many planets in the space?

There are eight planets.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

There used to be nine: Pluto was the ninth. Scientists have determined that it does not have the character of a true planet.

What is the character of a planet CJ? Fun-loving? Good sense of humour? Hard working?

Dear Dave P

I liked your answer. I think the character of a non-planet is "one that has not cleared the neighbourhood around its orbit"

[Depending on your neighbourhood, you may know characters like that]

It depends on the planet. Jupiter is very fun-loving. Venus likes to make love. Saturn is morose. And so on.

Pluto was just a Disney dog.

(Should I have said "characteristics"?)

Sorry, I couldn't resist.

Seriously, it seems to depend on whether the would-be planet is still surrounded by many other small space objects. If so, i

Hi Dave

Thanks for that

I like the forums very much: they are already quite challenging!

But I will give what you say some thought..

Best regards, Dave

Aren't there millions of planets in space?

Mister MicawberAren't there millions of planets in space?

Probably, but far fewer than that have been discovered so far, and only the eight in our own system have proper names.
