Because Earth's solar day is now slightly longer than it was during the 19th century due to tidal deceleration, each day varies between 0 and 2 ms longer than the mean solar day. [158] [159] Earth's rotation period relative to the fixed stars, called its stellar day by the International Earth Rotation and Reference Systems Service (IERS), is ...
In terms of Earth's rotation, the average day length is about 360.9856°. A day lasts for more than 360° of rotation because of the Earth's revolution around the Sun. With a full year being slightly more than 360 days, the Earth's daily orbit around the Sun is slightly less than 1°, so the day is slightly less than 361° of rotation.
One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi). [2] Ignoring the influence of other Solar System bodies, Earth's orbit , also called Earth's revolution , is an ellipse with the Earth–Sun barycenter as one focus with a current eccentricity of 0.0167.

100 days, roughly equivalent to 1/4 of a year (91.25 days). In Chinese tradition "bǎi rì" is the hundredth day after one's birth, also called Baby's 100 Days Celebration. semester: 18 weeks: A division of the academic year.

After the solstice, every day will have a little more sunlight than the one before. By the time we reach the summer solstice on June 20, 2025, it will be the longest day of the year.
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
