Chapter 677 Page 9. The Earth is clearly shown with a curvature. Hence, the Naruto's planet is spherical, like the Earth. As for the Infinite Tsukuyomi reaching the other side of the planet, I think Mecha Naruto got it right. The light either penetrated the Earth to the other side, or somehow some of the light of the Infinite Tsukuyomi followed a curved path to hit the darker half.
