The sky appears blue not because the air itself is blue, but because air molecules scatter the blue light from the Sun more strongly than other colors — a phenomenon known as Rayleigh scattering.
Matahari adalah reaktor fusi nuklear gergantik yang dalam setiap saat menghasilkan tenaga setara dengan lebih empat juta tan bahan peledak TNT melalui proses penggabungan atom hidrogen menjadi helium.
Venus rotates on its axis in the opposite direction of Earth and most other planets — meaning on Venus, the Sun rises in the west and sets in the east.
A white dwarf, or white dwarf star, is a very dense star — with a mass equivalent to the Sun but as small as Earth. Stars like the Sun, which are not heavy enough to collapse into neutron stars or black holes, will become white dwarfs at the end of their lives. Sirius B, the smaller component of the Sirius binary star system located 8.6 light-years away, is the nearest known white dwarf.
Since 2018, astronomers have confirmed the existence of a small celestial object approximately **70 meters** in diameter, named 2020 CD3, which periodically becomes gravitationally trapped in Earth’s orbit as a 'temporary moon'. Even more surprising is the discovery of another object—2006 RH120—which orbited Earth for a full **18 months** during 2006–2007. Neither is an ordinary asteroid, but rather a 'minimoon'—a temporary natural satellite captured by Earth’s gravity due to complex gravitational interactions among Earth, the Moon, and the Sun. This phenomenon is not speculative theory, but a verified reality of orbital dynamics, confirmed through N-body simulations and telescopic observations at the Mount Lemmon Observatory and Pan-STARRS in Hawaii.
Although its name suggests otherwise, only young sunflowers exhibit heliotropism — the movement of following the sun — while mature flowers remain permanently facing east.
