Space Facts: Part 4 - Celestial Dust, Kepler 289

-

1. What is Celestial Dust:

Cluster of galaxy: Abell 1698,
A1698-ZD1 galaxy in galaxy cluster of Abel 1698 is full of space dust. Dust is made up of Silicon, Iron, Oxygen, Magnesium, Carbon, etc. Elements and dust are formed in stars by nuclear processes from gases like Helium and Hydrogen. When star dies dust and gases are emitted. So dust was formed only after bigbang happened.

2. Kepler 289 Star:

PH3c (Kepler 289c) is a dwarf planet discovered in solar system of PH3 star. PH3c planet has irregular revolution time due to external gravitational force from other planets affecting the planet's revolution. Other planets of that solar-system are PH3b (Kepler 289b) and PH3d (Kelper 289d). 

PH3b and PH3d planets are very massive in size as compared to PHc so they pull the planets towards themselves when PH3 passes near them, changing the revolution orbit of PH3c. Astronomers estimate that after millions of years PH3c will be removed outside solar system by gravity-pull of the two massive planets and PH3c will become an Exoplanet.

3. Other Facts:

US708 is the fastest star discovered ever with speed of 1200 Km/sec.
Vales Marines canyon of Mars is 4500 Km long.
Ceres and Vesta are dwarf planets found in Asteroid belt of our solar system between orbit of Mars and Jupiter.
Arsia Mons and Olympus Mons are  volcanoes of Mars. Olympus Mons is largest volcano of our solar-system. Largest volcano on earth is Mauna Loa in Hawaii.
