Hi Celine,

I've not done this course so can't talk through the detail of it. It's been three days, so I hope you've got through this already; apologies for the delay in responding.

However, from the what the question is asking, the first part needs the following code in the .h file:

obj-c.h 
+(ColoredCircle *) asteroid;

and the following code in the .m file, recalling the properties that were requested in the first part of the challenge:

obj-c.m 
+(ColoredCircle*) asteroid {
  ColoredCircle*asteroid = [[ColoredCircle alloc] initWithDiameter: 1.5 andColor: @"grey"];
}

Rightly or wrongly, that get through the challenge compiler although it does seem to lack much of the code you'd expect!

I hope that helps,

Steve.
