No planets are mentioned by name, however, 'stars' is referred to about 55 times in the New International Version - obviously this would include planets.
The Earth is round like a circle:
Isaiah 40:22New International Version (NIV)
22 He sits enthroned above the circle of the earth,
and its people are like grasshoppers.
He stretches out the heavens like a canopy,
and spreads them out like a tent to live in.
they're both round
There are no planets orbiting the Earth because all eight of them orbit the Sun. But the Moon orbits the Earth, and all it does is go round and round in a rather complicated orbit which is disturbed by the Sun's gravity.
Please kindly note planets revolve round the sun only.
The circumference of a planet is the distance round their widest part. On earth, it is measured round the equator.
Copernicus
The Earth describes and ellipse as it revolves round the Sun (all planets do).
The Bible does not explicitly state that the Earth is round. However, some believe that references to "the circle of the Earth" in Isaiah 40:22 may suggest a spherical Earth. Additionally, some verses in the Bible describe the Earth as being suspended in space, indicating a spherical shape.
Jupiter is twice the mass of all the other planets combined. It is more useful and more accurate to refer to the mass of planets, and not to their weight.
Because the Earth and all the planets move in orbits round the Sun, while the stars appear to be fixed if we disregard the Earth's daily rotation.
When the Earth rotates from west to east, it produces wind in east to west direction and because of this friction occurs in between them which has turned the Earth round in shape.
The Holy Bible. It stated in the Bible that the Earth was a sphere long before humans realized it was. People chose not to believe, and it turns out that the Bible was right.
the earth is not perfectly round, as with most other planets it is an oblate spheroid. Answer: The tilt refers to a tilt in the axis of rotation, compared to a line that is perpendicular to the Ecliptic (the plane of Earth's orbit around the Sun).
