I only know how to find south - but not using the moon or Orion's Belt. Using the Southern Cross. But I don't think that's what you're looking for. :?

Sorry folks, I think I confused everyone by saying north :redface: but as Imberbe said if you know where south is you probably know where north is :wink:
I was using this

Seeing as Freda said anyone here is an easy one

What is the jewel box and where would I find it?

Here ! :twisted:

No, seriously, the Jewel Box (NGC 4755) is an open cluster (open clusters are physically related groups of stars held together by mutual gravitational attraction), discoverd by Abbe Lacaille when he visited South Africa during 1751-1752, and one of the youngest known, with an estimated age of only 7.1 million years.

The name Jewel Box comes from the great variety of star colours in this open cluster. One of the bright central stars is a red supergiant, in contrast to the many blue stars that surround it.

The cluster looks like a star to the naked eye and appears close to the eastern-most star of the Southern Cross, so is only visible from southern latitudes.

Thanks, Jeanus.

How can you you tell, with the naked eye, if a particular object you see in the sky is a planet or a star ?

Twinkle, twinkle little star!

A planet "shines" without twinkling.

It's Valentines. So lets talk about the moon.

Name two important things the moon does to the earth, that has a major influence on live on earth.

Helps regulate the oceans tides, earths gravetational pull and earths revolutions around its axis????

1. Ocean tides: :thumbs_up: The moon and to a lesser extent the sun creates the tides.

2. ?

You are somewhere in the right direction with your axis idea Jeanus. But not there yet.

Not only the tides bulge with the moons gravitational pull but the Earth bulges slightly ahead of the point directly beneath the Moon. So the force between the Earth and the Moon is not exactly along the line between their centers producing a torque on the Earth and an accelerating force on the Moon. This causes a net transfer of rotational energy from the Earth to the Moon, slowing down the Earth's rotation

By the way there are also studies that indicate that the phase of the moon can affect earths temperature possibly by modulating the influx of meteoric dust affecting the solar heating of the earth by absorption.
