the furthest planet
from the sun





Like many planets, Neptune’s orbit
isn’t exactly circular. Instead, Neptune orbits the Sun
in an elliptical orbit. At its closest point, Neptune gets within 4.45 billion
km, and then
orbits out to a distance of 4.55 billion km. It takes almost 165 years
to complete one orbit around the Sun.


It’s a shame Pluto isn’t a planet any
more, because it’s really far. Pluto gets as close as 4.44 billion km. But its
orbit is so elliptical that it gets out to a distance of 7.38
billion km. In fact, there are times in Pluto’s orbit when Neptune
passes it. Then
Neptune really is the farthest planet from the Sun, whether or not
you think Pluto is a planet.


What’s farthest object
from the Sun?
Astronomers think that the long period comets come from a region of the Solar System known
as the Oort
cloud. It’s possible that this region extends out from the Sun to
a distance of
50,000 astronomical units (1 AU is the distance
from the Earth to the Sun).


Here’s an article that lists the distances
to all the planets.


And here’s an article from Solar Views
that talks about the Oort Cloud.


We have recorded an episode of Astronomy
Cast just about the Sun called The Sun,
Spots and All.




Largest Mammal
on Earth


Blue whale is not only the largest mammal on earth, but
also bigger than any living creature. Everything related to Blue whales is
gigantic. The length of these cetaceans can be more than 100 feet, while their
weight is around 170 metric tons. It is said that a Blue whale's tongue
weighs more than that of an African elephant! The zoological name of this sea
animal is Balaenoptera musculus. Musculus is a Latin word meaning
"muscular". The Blue Whale comes from a family which includes the Humpback
Whale, Fin Whale, Sei Whale and the Minke Whale. Earlier, it was also
identified by names like 'Sibbald's Rorqual', Great Blue Whale and the Great
Northern Rorqual.



the highest mountain
in the world



Mount Everest is officially the highest mountain in the world,
with its highest peak at 8,848 metres (29,029 ft)
above sea levels. Climbing on the Everest is not that hard, but that doesn’t mean
anyone can do it. Specialized help is needed and that doesn’t come in cheap,
not to mention the gear needed. 210 died while trying to climb the Everest,
most of them
in the “death
zone” where
the conditions are extremely critical (the amount of
oxygen cannot sustain human life).



the Smallest
Ocean in the World



The
smallest ocean in the world is the Arctic Ocean. It has very complex and
sometimes disputed borders, but it surrounded by Canada, Norway, Russia and the
United States. The Bering Strait separates the Arctic Ocean from the Pacific
Ocean in the west and the Greenland and Labrador Seas separate the Arctic Ocean
from the Atlantic Ocean in the east. The Arctic Ocean is approximately one and
half times the size of the United States and is covered in varying thicknesses
of snow and ice for much of the year.


The
Arctic Ocean is being monitored very closely for the effects of climate change.
The decreasing size of the Arctic ice pack is affecting the Earth’s albedo
(reflectivity). The ice cap serves to deflect the sun’s rays back out to space,
stopping the absorption of excess heat from the sun. Without this layer of ice,
the ocean absorbs this heat, further melting the ice pack and introducing fresh
water into the system, disturbing both ocean currents and ocean salinity.
A
number of animals call the Arctic Ocean their home including the endangered
walruses and whales. Of the whale species found in the Arctic Ocean, the
Beluga, Bowhead, and Grey are endangered or threatened.





the world's
largest volcano


Hawaii Volcanoes –
Mountains

As you move along the chain
of islands in
the south, where Hawaii Volcanoes
are active,
the north-west of the old chain of volcanoes –
and less active. Active volcanoes erupting type of rock known as
basalt.




Mauna Loa is considered the largest active volcano on
earth, even if it is not broken out since 1984. But Kilauea, Hawaii Vocanoes
National Park, is the most active volcano in
terms of amount of lava that erupts every year, and visitors are more place to
see the volcanic
activity.


Hawaiian ancients believed that Kilauea was the physical
manifestation of the fury of the goddess mountain, Pele. Kilauea has added
550 acres of coast after the eruption began in March 1983. (See how big
this is, imagine that this is enough to fill more than 200 million





the deepest lake in
the world



Lake Baikal (Russian: о́зеро Байка́л, tr. Ozero Baykal, IPA: [ˈozʲɪrə bəjˈkɑl];
Buryat: Байгал нуур, Mongolian: Байгал нуур, Baygal nuur, meaning "nature
lake"[3]) is the world's oldest[4] at 30 million years old and deepest
lake with an average depth of 744.4 metres.


Located in the south of the Russian region of Siberia, between
Irkutsk Oblast to the northwest and the Buryat Republic to the southeast, it is
the most voluminous freshwater lake in the world, containing roughly 20% of the
world's unfrozen surface fresh water


At 1,642 metres (5,387 ft),[1] Lake Baikal is the deepest[7] and
among the clearest[8] of all lakes in the world. Similarly to Lake Tanganyika,
Lake Baikal was formed as an ancient rift valley, having the typical long
crescent shape with a surface area of 31,722 km2 (12,248 sq mi), less than that
of Lake Superior or Lake Victoria. Baikal is home to more than 1,700 species of
plants and animals, two thirds of which can be found nowhere else in the
world[9] and was declared a UNESCO World Heritage Site in 1996.[10] It is also
home to Buryat tribes who reside on the eastern side of Lake Baikal,[11][12]
rearing goats, camels, cattle and sheep,[12] where the regional temperatures
vary from a minimum of −19 °C (−2 °F) in winter to maximum of 14 °C (57 °F) in
summer.[13] Lake Baikal is nicknamed "Older sister of Sister Lakes (Lake
Khövsgöl and Lake Baikal)".


the fastest bird in
the world






The fastest bird in the world, the peregrine falcon is a welcome
recent arrival to London’s skies. Normally nesting in coastal cliffs and in
mountain areas, peregrine have taken to breeding on tall buildings and preying
on a wide range of birds including pigeons. One or two pairs are known to breed
each year in the capital, and they can sometimes be seen around the chimney of
the Tate Modern, or over Regent’s Park.



the highest waterfall



1. Salto Angel, (Salto Churún Merú)


Country: Venezuela


Location: Canaima National park


River: Gauja (Rio Gauya), tributary of
Rio Churún. The last in turn is tributary of Rio Caroni. The name - Gauja - to
the river has been given by Latvian Alejandro Laime, who was the first to reach
this waterfall by land. The other Gauja river is located in Latvia - in fact it
is among the most beautiful rivers of Latvia. Often there is made mistake by
telling that this waterfall is on Rio Churún.


Height: 979 m


Other information: At the lower part
the waterfall is 150 m wide. Europeans discovered the waterfall in 1935.
Waterfalls is named after James Angel - American adventurer, who had to make an
emergency landing with his plane nearby in 1937.
