The Moon is merely a black circle with a GaussianBlur effect to blend and
smooth the edges, as implemented in Listing 7.9.

Listing 7.9 Moon

public class Moon extends CustomNode {
public var centerX:Number;
public var centerY:Number;
public override function create(): Node {
Circle {
centerX: bind centerX
centerY: bind centerY
radius: 50
fill: Color.BLACK
effect: GaussianBlur { radius: 10 }
}
}
}

The SunBurst is an ellipse with a white fill, again using a GaussianBlur effect
to diffuse the color. This is illustrated in Listing 7.10.

Listing 7.10 SunBurst

public class SunBurst extends CustomNode {
public var centerX:Number;
public var centerY:Number;
public override function create(): Node {
Ellipse {
centerX: bind centerX
centerY: bind centerY
radiusX: 50
radiusY: 30
fill: Color.WHITE
effect: GaussianBlur{ radius: 30 }
rotate: 45
}
}
}

Totality is a set of solar flares rotating around the center point of the Sun out-
side of its main diameter. The SolarFlare is an Arc with a GaussianBlur effect
to diffuse the yellow color. Listing 7.11 shows the SolarFlare class.
