Al-Watan ACHA UONGO, JUA HALIMOVE KWENDA SEHEMU YOYOTE ILE, KWANZA JUA SIYO SOLID, SASA LITAWEZAJE KWENDA SEHEMU NYINGNE? LABDA KAMA UNAMAANISHA LINASPIN PALEPALE LILIPO NA HALIJONGEI KULINGANISHA NA DUNIA AU MWEZI. JUA LIPO PALEPALE.
Kumuita mtu muongo, kwa tuliolelewa na kufunzwa, ni tusi kubwa. Sijui kama umelelewa na kufunzwa, kwa hiyo sitaki kukupa uwezo ambao labda huna kwa kulichukulia tusi hili maanani.
Nimeweka link hapo juu awali inayoeleza jua linazunguka Milky Way galaxy, na Milky Way galaxy inazunguka center of local group.
Ila sina hakika kama unaelewa hii lugha.
Kama unajua Newtonian physics utajua sababu ile ile inayofanya dunia kuzunguka jua, ndiyo ile ile inayofanya jua kuzunguka center of the galaxy.It is just a matter of gravity.
NASA wameadnika hapa chini.
Bishana na NASA sasa.
Usipende kuita watu waongo kwa vitu usivyovijua.
Does the Sun move around the Milky Way??
Question:
Does the Sun move around the Milky Way?
Answer:
Yes, the Sun - in fact, our whole
solar system -
orbits around the center of the Milky Way
Galaxy. We are moving at an average velocity of 828,000 km/hr. But even at that high rate, it still takes us about 230 million years to make one complete orbit around the Milky Way!
The Milky Way is a spiral galaxy. We believe that it consists of a central
bulge, 4 major arms, and several shorter arm segments. The Sun (and, of course, the rest of our solar system) is located near the Orion arm, between two major arms (Perseus and Sagittarius). The diameter of the Milky Way is about 100,000
light-years and the Sun is located about 28,000 light-years from the Galactic Center. You can see a drawing of the Milky Way below which shows what our Galaxy would look like "face-on" and the direction in which it would spin as viewed from that vantage point. Also shown, is the location of the Sun in the big picture view of our Galaxy.
