Asteroid Field Around Sun

So I am trying to populate an asteroid field where each asteroid is connected to an array, then the field rotates around the sun, and the earth. So far I have the earth rotating around the sun, and the field appears as a huge square of static that rotates around the sun. How can I make that field into a circle of asteroids around the sun (center)?

var backgroundie;
var suntext;
//var astertext;
var earthtext;
var data;
var ang;
var rad;
var zoom = 1;
var nea;
var asteroids= [];
function preload(){
    nea = loadStrings('nea.csv');
    backgroundie = loadImage('stars.jpg');
    suntext = loadImage('suntext.jpg');
    earthtext = loadImage('earth.jpg');
    //astertext = loadImage('aster.jpg');
}
function setup(data){
    cursor(CROSS);
    createCanvas(innerWidth,innerHeight, WEBGL);
    translate(width/2,height/2);
    //imageMode(CORNER);
    //image(backgroundie,((innerWidth/2)*-1),((innerHeight/2)*-1),innerWidth,innerHeight);
    for(var i = 0; i < nea.length; i++){
        var data = nea[i].split(',');
        var name = data[0];
        var type = data[1];
        var sma = data[2];
        var e = data[3];
        var value = data[4];
        var profit = data[5];
        var accel = data[6];
        var moid = data[7];
        var group = data[8];
        asteroids.push(new Asteroid(name,type,sma,e,value,profit,accel,moid,group));
        console.log("for loop");
    }
}
function draw(){
    background(12);
    push();
    texture(suntext);
    rotateZ(frameCount * 0.01);
    sphere(30);
    texture(earthtext);
    translate(0,300,0);
    sphere(10);
    translate(0,-300,0);
    field();
    console.log("done");
    pop();
}
function field(){
    for(var i=1; i<500; i++){
        asteroids[i].display(); 
    }
}
function Asteroid(name,type,sma,e,value,profit,accel,moid,group){
    this.name=name;
    this.type=type;
    this.sma=sma;
    this.e=e;
    this.value=value;
    this.profit=profit;
    this.accel=accel;
    this.moid=moid;
    this.group=group;
    this.display=function(){
        push();
        ambientMaterial(41,41,41,100);
        //console.log("Function Processed");
        translate((random(30,250)),(random(30,250)),0);
        sphere(1);
        //console.log("Sphere Created");
        pop();   
    }
}
