Sirius is the brightest star in the night sky At a distance of 8.6 ly. Its name is derived from the Greek word Seirios, lit. 'glowing' or 'scorching'.
Sirius is gradually moving closer to the Solar System, so it is expected to slightly increase in brightness over the next 60,000 years. After that time, its distance will begin to increase, and it will become fainter, but it will continue to be the brightest star in the Earth's night sky for approximately the next 210,000 years.
1. First spacecraft to study a star - Our Sun.
The Parker solar probe, launched on August 11, 2018 is a part of NASA’s ‘Living With a Star’ program.
This probe will attempt to study two sections of the Sun: the corona and its atmosphere.
2. First mission to be named after living person.
The Parker solar probe gets its name from physicist Eugene Parker, who provided concepts to the energy generating capabilities of stars.
3.Closest distance of any spacecraft from Sun.
This distance will reduce to 3.8 million miles (6.12 million km) by the final orbits of the Parker spacecraft around the sun.
Forget Betelgeuse, These days, V Sagittae is so faint it's hard to find up there, even with a mid-sized telescope. But over the next few decades, as it's sucked into a nearby white dwarf, all of that could change.
Experts at Louisiana State University (LSU) think this pair of celestial underdogs is destined to become the most luminous star in the Milky Way galaxy, brighter even than Sirius, which currently holds the top spot.
At least, that is, for some 60-odd years. As the star and its dwarf companion gradually become one, their merge is set to create the explosion of a lifetime.
Saturn is the sixth planet from the Sun and the second-largest planet in our solar system.
Nine Earths side by side would almost span Saturn’s diameter. That doesn’t include Saturn’s rings.
Saturn takes about 10.7 hours (no one knows precisely) to rotate on its axis once—a Saturn “day”—and 29 Earth years to orbit the sun.
Saturn is a gas-giant planet. Saturn's atmosphere is made up mostly of hydrogen (H2) and helium (He).
Saturn has 53 known moons with an additional 29 moons awaiting confirmation of their discovery—that is a total of 82 moons.
