如图，A为太阳系中的天王星，它可视为绕太阳O做轨道半径为R₀，周期为T₀的匀速圆周运动，天文学家长期观测发现，天王星实际运动的轨道与圆轨道总有一些偏离，且每隔t₀时间发生一次最大偏离，形成这种现象的原因可能是天王星外侧还存在一颗未知的行星B，假设行星B与A在同一平面内，且与A的绕行方向相同，它对天王星的万有引力引起天王星轨道的偏离，由此可知推测未知行星的运动轨道半径是（　　）

A：R₀ $\frac{t_{0}}{t_{0} - T}$

B：R₀ $\sqrt{{(\frac{t_{0}}{t_{0} - T_{0}})}^{3}}$

C：R₀ $\sqrt[3]{{(\frac{t_{0} - T_{0}}{t_{0}})}^{2}}$

D：R₀ $\sqrt[3]{{(\frac{t_{0}}{t_{0} - T})}^{2}}$
