112 years after the Titanic sank, the story of the technological triumph-turned-tragedy still captivates many people.

Here are the answers to 18 common questions about the Titanic.

1. Who Built the Titanic?

Northern Ireland shipbuilding firm Harland & Wolff built the RMS Titanic from a design by its general manager Alexander Carlisle and naval architect Thomas Andrews. The Belfast-based company, which was founded in 1861, is still operating today.

2. How Long Was the Titanic?

The ship was about 882.5 feet long (that's 269 meters) and approximately 92.5 feet (or 28.2 meters) at its widest, the Titanic cost over $7.5 million to build. That's the equivalent of about 11 blue whales long and one blue whale wide.
The Titanic had two sister ships, the Olympic and the Britannic.

3. Where Did Titanic Set Sail From, And Where Was It Headed?

The opulent ship set sail from Southampton on April 10, 1912. To travel first class, the ticket would cost $4,700. It stopped in Cherbourg, France, and Queenstown, Ireland, before heading toward its final port of call: New York City.

4. How Many People Were Traveling on the Titanic?

After gaining and losing passengers in both Cherbourg and Queenstown, there were more than 2200 people passengers and crew onboard the ship. The exact number is not known: several authorities offered slightly different counts during the investigations of the sinking. The ship was not filled to its capacity, though.

5. When Did the Titanic Sink?

The ship set sail from England on April 10, 1912 and sank five days later, on April 15, 1912.
It hit an iceberg at approximately 11:40 p.m. on April 14 and went down 2 hours and 40 minutes later, at 2:20 a.m. on April 15.

6. Where Did the Titanic Sink?

The Titanic sank approximately 400 nautical miles south of Newfoundland, Canada.

7. Why Did the Titanic Sink?

Despite several ice warnings, the Titanic continued traveling at 22.5 knots (nearly its maximum speed) and was unable to turn quickly enough when an iceberg was spotted directly ahead of the ship.
It took a glancing blow from the iceberg, which created a gash that was between 220 and 245 feet long, it damaged at least five of the 16 watertight compartments meant to keep the vessel afloat, sending an overwhelming amount of water into the ship.
It is believed that if only four compartments were damaged the ship could have stayed afloat.

8. How Many Lifeboats Were There?

The Titanic had 16 lifeboats and four collapsible Engelhardt lifeboats, which were enough to accommodate a total of 1178 people. Surprisingly, this number of lifeboats actually exceeded the British Board of Trade requirement at the time, which had been enacted when passenger ships were much smaller and therefore required fewer lifeboat berths.
Among those were women and children, which Captain Edward J. Smith ordered board first.

9. How Many People Died?

Of the more than 2200 people aboard Titanic, an estimated 1500 died when the ship sank.
Among the death toll, were passengers and crew, including the band which played until minutes before it fully submerged.

10. Were There Any Notable People Traveling on the Ship?

As a luxury ship, there were many notable people of the era aboard:
Socialite Margaret "Molly" Brown, known for her brash attitude and flamboyance, was one of the lucky survivors.
John Jacob Astor IV was the wealthiest person on board, and $2400 was found on his body after he froze to death clinging to the side of a raft. Macy's co-owner and former U.S. Congressman Isidor Straus and his wife, Ida, also went down with the ship, as did the ship's architect, Thomas Andrews. There were several other high society figures on board, but there are others—like the musicians who continued to play as passengers boarded lifeboats—who have become famous because of the sinking.

11. How Many People Survived?

There were 705 survivors of the disaster.
Millvina Dean, who was only 2 months old at the time, was the oldest survivor until she died in 2009.
Charles Joughan was the only man to survive in the freezing Atlantic water.
Daniel Buckley disguised himself as a woman to save himself and get aboard the lifeboat. He succeeded.

12. Why 'Californian' Didn't Help Titanic?

The Californian did not help for two main reasons – it was not as close as once believed, and the Titanic's distress signals were unclear.
When the distress signal was sent out, the closest ship was The Carpathian. However, it was over 58 miles and 4 hours away.

13. Who Found the Titanic?

A team led by oceanographer Robert Ballard found the wreckage of the Titanic in 1985 while on a top-secret naval operation hunting down two sunken nuclear submarines. The United States Navy never gave him direct permission to search for Titanic, and when he discovered it, they were worried that the unavoidable publicity of such a find would reveal what they were really doing.

14. Who Owns the Titanic?

That's a complicated question. Admiralty Law details that sunken vessels in international waters are ownerless, but the U.S.-based RMS Titanic, Inc. claims status as salvor-in-possession. So if you got some souvenirs from the ship, you could sell them anywhere but the United States (where they would likely be seized).

15. Can People Visit the Site of the Titanic?

Technically, there's nothing stopping anyone from visiting the wreckage, which is resting approximately 12,500 feet—or about 2.37 miles—below the surface of the water. However, it would cost more than $250,000 a day to finance a dive down there, as it would require a ton of specialized equipment, diving expertise, and a whole lot of courage.

16. Is There a Titanic Museum?

Fortunately for those of us who don't have $250,000-plus to blow on a one-day trip below the ocean, there are dozens of Titanic museums throughout the world to visit. In addition to the largest Titanic museum experience in Belfast (where the ship was built), there are also artifact exhibitions everywhere from Las Vegas to Halifax, Nova Scotia (where many of the unidentified victims of the sinking were buried). There are also two RMS Titanic half-replicas in the United States (one in Branson, Missouri, and another in Pigeon Forge, Tennessee, not far from Dollywood) which boast a detailed likeness of, and artifacts from, the ship.

17. Can the Titanic Be Raised from the Ocean Floor?

The Titanic will never be brought to the surface. It remains a memorial site for those passengers and crew who lost their lives that fateful night. At 11.40 p.m. on April 14, 2012, under the light of the moon and candlelight, wreaths were dropped over the wreckage of the ship to honor the dead.

18. Is the Titanic Still Popular?

"The Titanic has basically been in popular culture since the night it sank," including recent television adaptations, and notably the feature-length film, Titanic, which was released in 1997. Directed by James Cameron, it starred Leonardo DiCaprio and Kate Winslet.
To commemorate the centenary of the ship's tragedy, the film was re-released in 3D in cinemas during the Easter Weekend of 2012.
"My Heart Will We Go On", the theme song of the film, is one of the biggest selling singles of all time, and features as the first dance at many weddings.
