Any ideas how to model this in OpenSCAD? I am relatively new to modeling so
any suggestions would be appreciated.

linear_extrude( 4 )
hull()

Adding a few more lines of code turns it into a sun.  Thanks!  This has been
fun!

WARNING: Before you actually try to Render (F6) that, change these two lines:

module ray( r )
{
k = r / (3360);
for ( a=[0:20:3360] )  // <------------------- CHANGE TO THIS
{
translate( [ ka, 10sin(a), 0 ] )
scale( [ 1, 10-.009*a, 1 ] )
segment();
}
}

module segment()
{
rotate( [ 0, 90, 0 ] )
linear_extrude( 20 )  // <-------------------  CHANGE TO THIS
hull()
for (i=[-1:2:1])
{
translate( [ 0, i*5, 0 ] )
circle( 5 );
}
}

Ha-ha!  Coincidentally, that was the exact question I had for myself.

So, here's the final version of the sun.  The scale() at the top gives a
final result that I could, if I wanted, print on my 3D printer: 202mm x
202mm x 10mm, which is a little bit less that 1/2 inch.

Enjoy!

//*********************************
$fn = 24;

scale( [ 0.1, 0.1, 1 ] )
sun();

module sun()
{
rotate( [ 0, 0, 45 ] )
fourRays( 600 );

fourRays( 1000 );
}

module fourRays( r )
{
for (a=[0:90:270])
{
rotate( [ 0, 0, a ] )
ray(r);
}
}

module ray( r )
{
k = r / (3360);
for ( a=[0:10:3360] )
{
translate( [ ka, 10sin(a), 0 ] )
scale( [ 1, 10-.009*a, 1 ] )
segment();
}
}

module segment()
{
rotate( [ 0, 90, 0 ] )
linear_extrude( 10 )
hull()
for (i=[-1:2:1])
{
translate( [ 0, i*3, 0 ] )
circle( 5 );
}
}

Just start with the lowest module, segment().  You can call it by itself and
see what it does.  Then, each higher module does something with the
previously developed modules, step by step.

Actually, I've only been using my 3D printer and OpenSCAD for about 6
months.  Yes, there is a bit of a learning curve.  But, I've been
programming for over 45 years; I usually find OpenSCAD easier to use than
the graphics-oriented systems.  Enjoy!  Don't be afraid to ask questions
here and in other forums.
