String animation for a rotating player in pygame

Question

I have a rotating player around a point. I want it to look like the player is attatched to the the string. Here is my player and string class

class Player:
    def __init__(self):
        self.pos = [0, 0]
        self.orbital_angle = 0
        self.player = pygame.Surface((20, 20))
        self.player.fill((100, 200, 100))
        self.radius = [200, 200]
        self.center = [600, 300]
        self.speed = 0.005

    def draw(self):
        D.blit(self.player, (self.pos[0], self.pos[1]))

    def orbit(self):
        self.orbital_angle += self.speed
        self.pos[0] = self.radius[0] * math.cos(self.orbital_angle) + self.center[0]
        self.pos[1] = self.radius[1] * math.sin(self.orbital_angle) + self.center[1]

class String:
    def __init__(self, x, y):
        self.pos = [x, y]

    def get_angle(self):
        return math.degrees((-player.orbital_angle) + math.radians(90))

    def get_length(self):
        dx = player.pos[0] - self.pos[0]
        dy = player.pos[1] - self.pos[1]
        length = math.hypot(dx, dy)
        return length

    def surface(self):
        string = pygame.Surface((2, self.get_length())).convert_alpha()
        string.fill((0, 255, 0))
        return string

    def rotated_surface(self):
        return pygame.transform.rotate(self.surface(), (self.get_angle()))

    def draw(self):
        self.rect = self.rotated_surface().get_rect(center = self.pos)
        D.blit(self.rotated_surface(), (self.rect.centerx, self.rect.centery))

The string class just takes the orbital_angle of the player, which is in radians, converts it to degrees and uses that angle to rotate the string(which is just a pygame.Surface). According to my knowledge, this should work but the angle is off. The position of the string appears to change in the screen for some reason although i never changed it in the code and they are constant when i print the values out as well. Thanks for helping

Copy and paste code to see whats happening:

import math, sys, os, pygame
from pygame.locals import *

pygame.init()

win = pygame.display
D = win.set_mode((1200, 600))

class Player:
    def __init__(self):
        self.pos = [0, 0]
        self.orbital_angle = 0
        self.player = pygame.Surface((20, 20))
        self.player.fill((100, 200, 100))
        self.radius = [200, 200]
        self.center = [600, 300]
        self.speed = 0.005

    def draw(self):
        D.blit(self.player, (self.pos[0], self.pos[1]))

    def orbit(self):
        self.orbital_angle += self.speed
        self.pos[0] = self.radius[0] * math.cos(self.orbital_angle) + self.center[0]
        self.pos[1] = self.radius[1] * math.sin(self.orbital_angle) + self.center[1]

class String:
    def __init__(self, x, y):
        self.pos = [x, y]

    def get_angle(self):
        return math.degrees((-player.orbital_angle) + math.radians(90))

    def get_length(self):
        dx = player.pos[0] - self.pos[0]
        dy = player.pos[1] - self.pos[1]
        length = math.hypot(dx, dy)
        return length

    def surface(self):
        string = pygame.Surface((2, self.get_length())).convert_alpha()
        string.fill((0, 255, 0))
        return string

    def rotated_surface(self):
        return pygame.transform.rotate(self.surface(), (self.get_angle()))

    def draw(self):
        self.rect = self.rotated_surface().get_rect(center = self.pos)
        D.blit(self.rotated_surface(), (self.rect.centerx, self.rect.centery))

player = Player()
string = String(600, 300)

while True:
    D.fill((0, 0, 0))
    pygame.event.get()

    string.draw()

    player.draw()
    player.orbit()

    pygame.draw.circle(D, (255, 255, 255), (string.pos[0], string.pos[1]), 2)

    win.flip()
