This morning you can see a waning crescent moon that will be in conjunction with Mars and Jupiter. The moon, Mars and Jupiter will be within a circle of 5 degrees in diameter. If you hold out your arm a circle with a 5 degree diameter is about the size of a closed fist. All three of these objects will be seen about an hour before sunrise. Below are two images of what this event will look like when you look towards the southeast horizon .

The moon will be at apogee. This means it will be farthest from Earth in its orbit and hence will appear slightly smaller looking.
